I have 1 bedroom, 1 office and a living room, I don't keep trash in the flat we have a storage unit, in fact unless we convert the 2nd bedroom/office to a closet we actually rotate clothes in and out of the storage unit because there isn't enough wardrobe space for 2 people for all seasons.
Tiny apartments are a health hazard they damage both your physical and mental health, they aren't any more environmentally conscious than properly sized apartments and this whole minimalism fad is complete horeshit litterarly sold too and by useful idiots.
A 6m^2 apartment is below what is legally can be called a room in the UK, In fact it's the size of a US prison cell (5.8m^2), 20m is blow the legal limit for a home which iirc is 37m2 but in the UK this only covers recent builds and conversion so you might still find 30m flats somewhere however depending on the council they are can be illegal to rent out.
For perspective this is what 6 square meters look like https://weburbanist.com/wp-content/uploads/2016/05/6x9-jail-...
So yes while I was a bit hyperbolic I don't understand how someone can live in a literal prison cell yet alone calling it more comfortable than living in a small hotel room. But no I don't to question my conscience regarding what I need or don't need, what I want is an apartment in an area I like, close to what I need and want to have, for a price I'm willing to pay. Besides that I would opt out to get the largest apartment I can, 2 baths is a must because I live with a partner, having an extra room for work and or guests is also nice especially since it allows us both to work from home on the same day and gives us some room from each other if things get too heated and I don't have to be in her face or one of us has to go out.
