We loved the apartment! It was spacious enough for 6 people and very clean! The location was terrific, in one of the most iconic streets of Lisbon, less than 5 min walk from Rossio where the Aerobus stops, 1 min walk from the Santa Justa Elevator and 1 min walk from the famous Santini ice cream shop, where we became regulars. :-).
The house manager, Taiz, was very nice and made us feel at home immediately. She had the bottle of wine ready in the fridge for us, when we arrived! ;-) She had plenty of tips for Lisbon and its surroudings.
The communication beforehand was clear and quick with Jose, which was really nice!
The only comment I can make, is about the showers. There are 2 bathrooms (which is very convenient for 6 persons), but unfortunately, when 1 person was showering, the other shower didn't work well (very low pressure). So, in the end, we had to wait for each other. If that can be fixed, it would be THE perfect apartment to stay when you're in Lisbon!
