We had a wonderful time in the apartment. The location is ideal, we can visit the city on foot as well as by public transport. The hosts are attentive, very reactive, have a sense of welcome! We recommend of course! Attention, for people who can't stand noise, I advise you to take your precautions, the bairo alto can be noisy at night, but it's part of Lisbon's charm and we stay there knowingly!
Conclusion: superb apartment, great hosts, go there with your eyes closed!
