Home and Accommodation

The answer opens with a two-word fragment ('An apartment.') and sticks to short, accurate sentences with only one basic relative clause ('which I like'), which is clear but deliberately plain for Band 6.5.

Do you live in a house or an apartment?

An apartment. I live alone in a small one-bedroom flat near the Han River, on the ninth floor. It doesn't have a balcony, but I can see the river from the kitchen window, which I like.

Why this band

• FC“An apartment.” — 'An apartment.' stands alone as a minimal, near-fragment opener before any of the following sentences add detail. This blunt directness is the Band 6.5 fluency target in its purest form — answer the question first, elaborate only afterward — and it contrasts with the softened, hedged openers ('if I'm honest') that appear in higher-band answers on the same topic. The plainness here is a feature of the level, not a weakness in content.
• LR“small one-bedroom flat” — 'Small one-bedroom flat' uses only common, high-frequency vocabulary to describe the home, with no attempt at a more specific term like 'studio' or 'compact unit'. This sits exactly at the Band 6.5 ceiling of 'everyday, high-frequency words. At most one slightly less-common word' — and here even that one slightly less-common word isn't used, keeping the description as plain as the target allows.
• GRA“which I like” — 'Which I like' is a relative clause added almost as an afterthought at the very end of the sentence, rather than integrated earlier or expanded with a reason. It's about as minimal as subordination gets while still counting as a complex sentence, matching the Band 6.5 grammar target of 'mostly simple sentences plus a few basic complex ones'. A higher-band answer would more likely explain what specifically is liked about the river view rather than leaving it as a bare relative clause.

The reason-plus-example move ('which makes it easier to get along' ... 'My favourite part is the tiny yard at the back') develops the answer beyond a bare description, which is what pushes it past 6.5 without reaching for unusual vocabulary.

Do you live in a house or an apartment?

I actually rent a small house with two flatmates, not far from Da Nang University. It's got two floors, so we each have our own room, which makes it easier to get along. My favourite part is the tiny yard at the back, where we grow a few pots of herbs and sometimes have dinner outside when the weather's nice.

Why this band

• GRA“which makes it easier to get along” — The non-defining relative clause 'which makes it easier to get along' attaches a consequence directly onto the earlier statement about each flatmate having their own room. Combining a simple factual clause with this kind of consequence clause is the comfortable mix of simple and complex sentences the Band 7.0 grammar target describes — accurate, natural, and not overreaching. A Band 6.5 answer would more likely present the same idea as two separate short sentences: 'We each have our own room. It's good.'
• LR“grow a few pots of herbs” — 'Grow a few pots of herbs' is a natural, functional collocation rather than a decorative or unusual word choice, and it adds concrete, sensory detail to what would otherwise be a generic mention of a yard. This is exactly the kind of single natural collocation the Band 7.0 lexical target asks for — 'mostly common words plus a few flexible or topic-specific ones; one natural collocation' — used for texture, not to impress. It also grounds the answer in a specific, personal image, herbs and dinners outside, rather than staying abstract.
• FC“My favourite part is the tiny yard at the back” — After the basic facts about the house, the speaker singles out one detail — 'my favourite part is the tiny yard at the back' — and follows it with the concrete example of growing herbs and eating outside. That move from bare fact to a chosen detail with a short supporting example is precisely the fuller development the Band 7.0 fluency target expects, one step beyond a Band 6.5 answer that would likely stop at describing the rooms.

The unusual living arrangement is rendered through one long, controlled sentence with a relative clause and a result clause ('close enough to the sea that I can smell the tide at night'), giving the answer real grammatical range.

Do you live in a house or an apartment?

A flat, technically, but an unusual one: the whole upper floor of a narrow family house, reached by a staircase that passes the owners' kitchen, so every trip home involves a greeting and, on a good day, a bowl of something. I have my own front door, a tiny balcony and the roof. It's the right size for one person and a bicycle, and close enough to the sea that I can smell the tide at night.

Why this band

• GRA“the whole upper floor of a narrow family house, reached by a staircase that passes the owners' kitchen” — The noun phrase 'the whole upper floor of a narrow family house' is expanded by a further relative clause — 'reached by a staircase that passes the owners' kitchen' — stacking two layers of modification into a single controlled sentence. That double expansion is more ambitious than the single relative clause typical of a Band 7.0 answer and matches the Band 7.5 grammar target of 'varied complex structures' used accurately. It also earns its complexity: the staircase detail sets up the payoff about greeting the owners on every trip home.
• LR“on a good day, a bowl of something” — 'On a good day, a bowl of something' is deliberately vague and understated — 'something' is left unspecified for wry effect rather than because the speaker lacks the word for it. That kind of idiomatic, register-aware aside is the 'figurative or idiomatic touch if it fits the moment' the Band 7.5 lexical target describes, used here to keep a slightly comic tone rather than to sound impressive.
• GRA“close enough to the sea that I can smell the tide at night” — 'Close enough to the sea that I can smell the tide at night' uses a result clause pattern (close enough...that) to link a spatial fact to a sensory consequence in one accurate, natural sentence. This is one of the varied complex structures the Band 7.5 grammar target expects, and it stays error-free while doing more work than a flat statement like 'It's near the sea' would.
