Enjoyable stay in Lisbon! The apartment is in a great location, a pedestrianised street right in the centre of town with many restaurants, close to the river and to a metro station.
The apartment is spacious with three bedrooms (two doubles, one twin), two shower rooms. There is air con in the 2nd and 3rd but not the main bedroom. Considering the busy street the apartment is on, the noise at night was ok, the 2nd and 3rd bedrooms both face that street but have shutters on the windows. We were able to check in early which was appreciated, the hosts were very flexible.
The living room has comfortable seating for 4 and a dining table with 4 seats so fine for our family but if more than 4 guests, more seating would be better.
The WiFi was very slow the whole stay even if close to the router, needs upgraded.
Overall I'd recommend the apartment.
