We were a group of 20 friends and had an amazing time in the apartment. Albertino was very responsive and helpful. The apartment was beautiful with wonderful wooden floors. It was spotlessly clean and there was plenty of room - it was actually much bigger than expected.
Location wise it was a great base from which to explore Lisbon with lots of places walking distance and others a short (and cheap) Uber ride away.
Would recommend to anyone looking for group accommodation in Lisbon.
