It was a great experience. The apartment is perfect in almost every way: location, services, attention ...
Paula and Alex are in charge of everything and you can have all the necessary information for a great time in Lisbon. The department it is located at walking time of the most emblematic places or the subway stations, so it facilitates much your displacements. And the facilities (rooms, beds, kitchen ...) are of great quality.
I would improve only one thing: showers can be taken only one person at a time with hot water, which can mean a delay with large groups. Anyway, the experience was very good and I highly recommend staying in the apartment.
