The location is great (not far from the subway and main sights) and for one night the place was completely fine and enough. The check-in and communication with the host was great too!
Just be warned that one can hear everything from the neighbours and street so bring ear buds to cover the noise. Additionally, there are no proper blinds/ thick curtains so it gets really bright in the room early in the morning. The bed is quite old, hard and squeaky when turning around at night which does not really help the comfort unfortunately.
We stayed one night inbetween arriving in Athens and leaving to an island and for that the room was sufficient and one gets everything needed for the price (incl A/C which was good).
