The location is perfect- it is just a 5-10 mins walk to the Acropolis area, and there are also a lot of excellent local restaurants around. Spyros team is very responsive. We got answers to our questions very fast, which was super helpful. The private patio is also a place where neighboring cats come to visit. The apartment is as described.
The only minus would be that there will be motorcycles till around 11 pm, given there is a Walt Marketplace right across the street. But we are late sleepers, so it was not a problem. We had a great stay there.
