The apartment is very spacious and perfect for five adults: two couples and one single person.
It was very clean and had everything you need. The building has an elevator as it is in the 12 floor and also a free parking space. Isabel was very nice and available at all times to reply any questions. We can only recommend this place!
PS: it is a bit far from the city center, but you can walk 25 mins to the Praça do Comércio, take a bus in the vicinity of the building (5 minutes walk max), or go to the Santa Apolonia train station 15 mins by walk. As Lisbon has a nice weather most of the time, all options are good according to your kind of trip!
