We stayed in Diogo's apartment at the end of July. The location of the appartemt is great! Very closed to the metro station and central in the middle of the vibrant part of the city. The apartment has everything you need. The kitchen is very well equipped. The bathroom was every clean. Diogo is a very nice host, he was alway available to answer any question. Our room was facing the street, which is very busy at night. I personally had no problem with the noise (I closed the windows and switched on the AC). Check in and check out was flexible and smooth. I recommend this place if you want to visit Lisbon.
