The apartment is very nice and clean and newly renovated. The air conditioning works well and the window blinds are awesome (if you like to sleep in). The WiFi works well and the TV has a good selection of channels.
The photos are bit stretched, misleading the impression of the size. (e.g. see the TV in the photo)
The bed is hard but not bad. There are extra linens and pillows if you need them. The kitchen is small but well appointed (for me this meant a tea kettle and coffee press :-) ).
Note, the water heater needs to be turned on in the fuse box.
The apartment is on the top floor, and there is an elevator, but it's a bit rickety, and small (but normal-European small).
The mini market next to the entrance is very nicely stocked and the owner is friendly.
This is close to a couple of metro stops; we always went to Omonia and it was less than a 10 minute walk.
The neighborhood is super sketchy. There are people loitering around (likely not sober) all day and especially at night. It smells really bad from the trash and human waste. I would not stay here if I were traveling alone; even as 2 we sometimes found another street to go down to get to the apartment. But, there are regular hotels and restaurants on this street. We were told it's supposedly not dangerous, just sketchy looking, but it felt very uncomfortable at night.
Overall, good value for money, but don't go here alone.
