Matteo's place was lovely for the first part of our Portuguese adventure. His friend checked us in and was very communicative and flexible. Overall the stay was great, but as others have mentioned, there is construction going on across the street from the flat, which can be a bit loud at times, but construction in Lisbon seems difficult to avoid and not something within Matteo's control. I'd recommend staying at Matteo's if you get a chance to visit Lisbon not only for the great flat, but also because the neighborhood is excellent and an easy walk to many great spots in Lisbon.
