Giacomo's unit is perfect for a couple spending a few days in Lisbon. I loved the location in Estrela neighborhood in a quiet residential street. The location is just a ways away from the main tourist hub, but Estrela itself is worth a stroll around and exploring too. For me and my wife, we really felt like we were seeing a part of Lisbon that most tourists miss (despite it having plenty of things for tourists to enjoy). It's a very short walk to any bus or trams you may want to take to get around in the city.
We went for our honeymoon, so my wife was very pregnant. The unit sits atop a hill. but is on the ground floor. For the tourist tram, it's relatively flat (for Lisbon) to reach. Some of the buses involved going down a steep hill to catch (and going uphill to come home to), but even my wife was not too bothered by that fact. The reality is Lisbon is hilly everywhere.
We slept so comfortably in the bed, there is AC in the bedroom. The bathroom is nice size with giant luxurious towels that we especially loved.
Giacomo doesn't provide much in the way of supplies (no soaps, for example. No waters or coffee pods). But that was not a problem. There are supermarkets closeby to quickly pick up those things after checking in.
