I was a bit worried about how the two of us would get on in such a small place for our 10 day stay in Athens, but actually we found the studio absolutely fine. It's well laid out and so never felt too pokey, plus we had nice enough weather to be able to use the balcony which was a huge bonus.
The place gets lots of light and there are windows everywhere, plus there is a vacuum so you can keep it tidy. The bathroom is the kind where showering gets water absolutely everywhere - but there's a big drain in the floor and leaving the window open dries it all out within an hour.
We missed having a washing machine and bought a few bits and pieces like a corkscrew and a decent knife to make the kitchen more useful, but all in all it felt very comfortable and like home.
Also self-check in with a lockbox was a lifesaver for us given our flight landed in Athens at 1am.
Sadly the host was totally unaccommodating when we asked if we could check out but leave a bag until 4pm before going to the airport. She insisted that we had to 'comply' with the 12 noon check out because that's when the cleaners would be coming.
Seemed a bit unnecessarily offhand given they had no one booked to come for another 2 days.
