I live in a one bedroom (I think it's 650 Sq ft). Moved here a year ago from another country with a few suitcases, very little "stuff", no furniture. I live alone, no pets (will not ever have pets in a small apartment). Up till a year ago I was living with ds in a small two bedroom/one bathroom (~700 sqft). I actually like this amount,t of space. I would love to have a small patio or balcony, as long as someone else is responsible for gardening, and I wouldn't mind having w/d in my unit instead of shared facilities downstairs. All in all, it's not terrible for a rental, it's what they call "garden apartments", lots of green, lots of open spaces.
When I will be in position to buy, I would like one more bedroom and possibly another bathroom, and a balcony. But I like the fact that it's small. I don't have a lit of stuff and I clean the house very quickly.
In a perfect world, if I had the money, I would love a beachfront house with a huge deck overlooking the ocean, a staff to keep everything neat, and still would be fine with two bedrooms
