We truly enjoyed our stay. The communication with Chiho and Nuno was excellent (quick responses, lots of information etc. very helpful when one doesn't know the country).
The flat is as described, very sunny, brand new with high quality furniture and appliances.
Very centrally located, close to all the touristic attractions, the metro, the shopping and supermarkets (even a Bio market within a walking distance).
Of course, being central and surrounded by restaurants, the area is very lively/noisy morning to evening... but I guess that is the counterpart of being in the heart of the city.
We recommend this appartment!
