We had a very nice stay in the apartment. The location in Principe Real is perfect, close to a lot of nice restaurants and shops (we enjoyed the ice cream at niva and the restaurants at plaza de flores), and right next to the botanical gardens. The host was very clear in the communication and quick to reply if we had any questions.
Even though some of the days of our stay were warm, we could get a good draught from the windows, and fans were also available in the apartment.
As the host states in the description, the building and apartment is old, so we did not expect it to be modern, and enjoyed the charm. All and all we had a great stay in Lisbon!
