We stayed for a month, and the apartment was excellent-comfortable and everything worked well. Chiado is probably the best neighborhood for a relatively short stay. In general, we thought Lisbon was one of the most friendly and hospitable cities we have ever visited. No doubt this was partly due to the extraordinary helpfulness of Antonio and Concepciao. They were wonderful hosts and it was a lot of fun to talk to them. But we also really liked the people who live and work on the street. Really great people and a great place.
