My wife and I had a wonderful stay at this Upstreet AirBnB. The apartment was immaculately clean, appears just as pictured. Huge amount of space for two people. There is a combined washer-dryer in the kitchen, meaning cycles take a very long time and capacity is very small, but running it overnight each night worked well and the convenience was fantastic. Quiet at night. AC units worked very well.
The location was extremely convenient, very close to Syntagma where it was easy to take buses (ie X95 to and from the airport) and the Metro, and was a short walk to most of the sights within central Athens. Just a few minutes' walk to a well-stocked grocery store as well.
It was straightforward to self check-in as well, though we had arrived a few minutes earlier and realized our door code didn't work until the official check-in time.
Overall, if we're back in Athens, we would definitely stay again! Highly recommend.
