Locationwise the airbnb was great. A really short walk from the Monastiraki metro station, and in a lively neighbourhood. Even the Alkropolis and shopping streets were within walking distance. The property was clean. The ToStay company answered our messages within a few hours.
We were disappointed that the airconditioning didn't work, when we specifically booked a place with airconditioning (to survive the Athens heat). After booking and reading recent reviews we could see that it had clearly been broken for a while and it wasn't fixed yet. The ToStay company that manages the property said they would send over a maintenance guy but the issue was never fixed...
For our multi day stay we were missing just a few basic kitchen things like a dustpan and brush, cleaning cloths/products, also a bathmat, an armchair/couch would have been appreciated. ( and oil, salt and pepper would have been nice).
It is a sufficient place to stay if you are out a lot.
