I had a great stay at Marios place. My room looked like on the photos and everything was exceptionally clean. The kitchen was well equipped and offered a big enough fridge.
Check-in and communication before and during my stay were flawless.
Location is not in the center, but close to it. I rarely needed public transportation.
Since the room is on the first floor, i´d recommend for light sleeper to bring ear plugs. Personally, i slept fine though.
I very much recommend this place, especially considering the good pricing.
