The apartment is very tiny but well equipped. We were there for a very short stay in (two nights) in between flying in to Greece and moving on to the islands and for this purpose it was fine. Mostly because it was extremely well located within a very short walk to direct metro lines from / to the airport and Pireus port, with lots of cool restaurants, bars and lively neighborhood. Babi was very helpful with check-in instructions but also provided us with suggestions on great restaurants and sightseeing attractions nearby.
The best feature of this airbnb, which to our surprise was not very loudly advertised in the listing, is the FABULOUS rooftop with an awesome view of the Acropolis. It makes up for the tinyness of the apartment! ;-) We had our breakfast there and enjoyed a lovely evening sipping wine and admiring the sun setting down over the city. Beautiful!
