This apartment was great for our trip to Lisbon. It is set in Barrio Alto which is a fantastic area to walk around and to go out at night (tons of bars and restaurants, including Fado Bars). We were also steps away from a main square and great bakeries. Also is only a few minutes away from tram 28 and metro.
With Uber being so easy and incredibly inexpensive here we found it so easy to get anywhere we liked.
The stairs were kind of a pain, especially with luggage (4 flights of stairs)
There was an issue where the apartment was not cleaned when we checked in, there was a delay and they came at 4pm. This was inconvenient but once fixed everything was good.
