We had a great stay overall !! The apartment is brand new and the beds are very comfortable. The kitchen is stocked with plates/pots/glasses and has a brand new oven as well as a Nespresso machine. The A/C units work well and if you prefer to sleep without and let the fresh air in, all windows have mosquito nets which is a nice touch.
Internet was reliable. There is a washing machine you can use (all commands are in Greek but the manual should be somewhere on top, or you can use the Google translate app to take a picture and translate automatically).
Our host was nice and very responsive if we needed anything !
The one thing I wish I had paid more attention to on the listing is that there's indeed no kitchen essentials in the house when you arrive (no paper towel, extra trash bags, nor a few coffee pods just to get started), which would have been nice if you're only staying for a few days. A couple detergent pods where provided on request though !
