This is a wonderful flat very close to the flea markets and the acropolis (the roof has a lovely view!). Check in is seamless and there is a luggage room if you are staying past check out or arriving early. Everything you could need is meticulously written in the notes and the hosts are very communicative. The flat is clean and provides hotel-like amenities.
The only few snags were that: (1) I was ravaged by mosquitos on my first night despite not having the windows open, so I’m not sure how they managed to get in. This was clearly an issue they had before because they had bug spray and a repellant for the room in the closet, but I didn’t get the diffuser for it until my second night. After that I slept well on night 2. (2) the walls are quite thin and so you may be able to hear conversations with your neighbors or street noise, and I could hear people walking up and down the stairs. It wasn’t too disturbing for me but might be if you are a heavy sleeper. (3) finally, I had an important zoom meeting during my stay and I had to connect my computer to my phone’s hotspot because the internet was unreliable. These were all mostly annoyances though and with this in mind I’d recommend here to stay!
