We stayed in Miguel's little appartement for a few days to explore Lisbon. It was a great base and within walking distance from Praça do Comércio. Miguel was really helpful and sent us lots of recommendations of things to do. He also left us a lovely bottle of wine.
The place was clean and as expected. The street was a little noisy at some points during the day/late in the evening, but it didn't continue into the night.
