The best location!!!! You are right in the center of the Monastiraki neighborhood where there are bars, restaurants, coffee shops, and a really big flea market nearby. There's literally a cute small bar right next to the entrance of the flat. There are also two metro stations a short walk away which was helpful, especially if you are coming from the airport.
The space was very spacious for two people. And let's talk about the rooftop. I only expected to have a small balcony from seeing the photos, but you have a balcony AND a whole rooftop to yourself! It's the perfect way to spend an evening with a bottle of wine and take in the awesome view of the Acropolis and all of the nearby rooftop bars.
Check-in and check-out were very easy. Host was communicative. We had zero issues. The only thing I would say is you have to climb three floors of stairs so it's a bit hard with heavy luggage. Other than that, would 100% stay here again!
