Fantastic place to stay in Lisbon. This apartment is in a wonderful location; easy walking distance to many restaurants, the cathedral is 2mins walk. We also walked to other visitor attractions (like the castle, lovely monastery at Igreja de Sao Vicente de Fora). The streets are cobbled and often steep so take your sensible shoes. We felt comfortable walking round this area any time of the day or night. Also handy for the trams (we took the tram along to Belem) and the Metro (easy journey to/from the airport).
The apartment was clean and had everything we needed. Comfortable bed, lovely thick, fluffy bath towels.
Nuno is a great host. We asked him for recommendations of where to see Fado, which he sent us straight away, and proved to be a fabulous experience. Restaurants nearby also have live Fado on some evenings, but we found the the specialist Fado restaurant a more moving.
