I stayed at Nuno's place with my 6 month old baby and parents for 3 nights. The apartment is in a very central location, just up the hill from Rossio Square. We were able to walk to all the major sights in Lisbon from the apartment. Nuno's brother, Rui, was my main point of contact while we were staying there and he was super attentive! We didn't get a chance to meet but I felt like if I needed anything he would be there to help. I got a good work out pushing the stroller up the hill to get the apartment - so in that way it's not ideal with a stroller. The apartment as it says is cosy but functional which is true! But I would say that it's enough room for 2 adults only. If you have to use the pull out couch, you won't have room for anything else or to do anything else. We really appreciated the complimentary pick up when we arrived in Lisbon and for all the thoughtful touches - pasteis de natas, juice, cheese, and bread! The crib for my baby was nice and comfy and everything in the apartment was clean. Considering you are very close to Rossio Square, the area is very quiet at night.
