Great location, within walking distance to the Acropolis, really communicative host, the place has everything you need, albeit a bit basic.
BUT
Please note that the flat is on a super busy road which gets very noisy, the aircon is very noisy, and the flat is located in a building that has some questionable tenants (massage parlour for VIP guests on the ground floor...) and there is only enough hot water for 2 guests at a time. If you are ok with this - good place to stay.
