Don't think twice! Dimitris place is even better than it looks, let me tell you: The location is incredible, less than 2 minutes walk to Monasteraki station, close to a lot of very tasty restaurants, cafes, bars, the flea market, many small supermarkets, shopping malls... You can walk to the Acropolis (or take the metro but I would really walk, it is beautiful) if you like and you will get to see some beautiful streets. Dimitris is a GREAT host, he recieved us and showed us the place, explained everything and gave us some tips to move around (he also had the fridge full of tasty greek things for us to have), also communication with him was super easy. The view is amazing, even better than what you see in the photo, you will feel soooo close to Acropolis you won't even want to close the curtins at night.
I highly recomend this place, you won't regret it. I will come back to Dimitris place for sure if we come back to Athens!
