Konstantinos's place was great. It's really close to the metro and there are lots of restaurants just down the street from the apartment. The space was perfect for us, (we were 5 in total) and Konstantinos was very accommodating even though we were only there for one night. We flew in from Santorini and we had another flight the following day at 10pm and he let us stay do a late checkout, which was great. Overall we had a great time and would definitely recommend his place.
