Quite bare bones.
Yes, there is a washing machine, but we had to go to the supermarket to buy washing powder. Yes, there is a bottle opener, but no wine glasses. Yes, there is a second bathroom, but no soap to wash your hands. Yes, there are knives, but only a small fruit knife and a bread knife (making cooking a challenge).
The apartment is quite bare and the experience was very impersonal. We picked up the keys from a machine and never met our hosts - we just exchanged a few SMS messages during the week we stayed there.
