The apartment is exactly as advertised. Simple, clean, and perfect for those looking to explore this great historic city.
My girlfriend and I never planned to spend the day in the apartment - we needed somewhere to leave our stuff as we were out exploring the city. Every night, we came back to a decent sized room with a double bed and enough space to get dressed in. Every morning, we woke up to a very decent shower and a big enough table for two to eat at, with a TV with enough options to keep on as background noise.
Many have commented on the location, but being from a city, the surroundings were really nothing to worry about. We were 5-8 minutes (depending on our energy levels) away from Thiseio / Monastiraki Square, which was ideal both to hang out in, as well as connecting to the Metro which got us to the tram after a few stops (once you're on the tram, you have numerous beach options). It goes without saying, the proximity to the Acropolis is a stones throw away, so you really can get all the main historic sites done (minus the museums) done within a day, with enough time to get home and have dinner in Thiseio.
When visiting Athens again, we hope the building has an empty apartment for us again.
