We enjoyed our stay at Nuno's apartment. It's in a great location and the space is really nicely furnished with all the amenities you need for a short break.
The building and neighborhood were really quiet. A small thing to note is that as it's an older building, the apartment did get quite cold during our stay in early March - so we'd take extra layers if we visited again in the winter months! Overall a lovely time in Lisbon. Thanks, Nuno!
