The place is very nice. We were only there one night only on our way to another part of Greece, but it was very close to the metro station which was a plus since we were tired from being on planes for a long time. The place is a few meters away from a main street so it is quiet at night yet no too far from areas with shops and restaurants (10 minute walk in average). There are several restaurants and coffee shops so you will not hungry at all.
The rooftop view of the Acropolis is amazing!...we got a bottle of wine and went upstairs to see the sunset. You can see a big part of the city, so I would recommend to do it at least one time.
Shower was decent as well as the water pressure. loannis was very helpful and accommodating since we had arrived a bit earlier than check-in time. This is a place I would definitely come back to.
