Bruno's apartment was perfect for me and my boyfriend during our 5 nights in Lisbon. Really made you feel like you were living in the heart of the city like a local rather than a tourist. Small but all we needed. Open plan, clean and nicely decorated. Kitchen good size. Bathroom was small but wasn't an issue for us. My only criticism of the apartment would be its lack of light and its dampness. Also the fact it was right on the street was not a problem until the night time when you could here a lot of what was going on outside. However these were not major issues for us and I would not at all regard them to have ruined our stay.
Bruno was also a great host. Although he was away he gave us advice on where to go and was helpful and reassured us that there would be family and neighbours to help us with any problems we may have.
I would recommend his apartment to anyone wanting a real Lisbon experience!
