I was in quarto 1 and really loved the view of the blue sky and the church. The quarter Graca has everything you need in terms of pastelerias, bars, restaurants, little and bis supermarkets and the 2 most beautiful miradouros of Lisbon are nearby the appartment. As there are always other guests you shouldn't be afraid of other people;-)
Jack and Roberto are there for any questions and are very warm-hearted.
I head a very nice stay, obrigada!!
