The most important thing to me is communication...from pre-booking through to check-out, it was immediate, helpful and friendly!
Before checking in & departing, baggage storage was allowed, which was a great bonus!
The apartment itself is in great condition and is situated in a quiet location, very close to both the Estrela Gardens and the infamous & 'touristy' 28 Tram. The tram 'stop' is at the end of the road and gets you into the Bairro Alto area very quickly...also enroute is the Rooftop bar for great sunsets!
Like all older buildings in Lisbon, floors or stairs may creak, (as some reviews may have commented on), but this did not create any disturbance at all and the occupiers of the apartments above and below, respected the management company's rule on the noise curfew time.
The apartment is great value for money and the management team is one of the most friendly and professional I have experienced since using Air BnB. I will certainly be staying again when next in Lisbon!
