We enjoyed our 3 day stay at Largo Sao Miguel. We felt a little bit as locals in Lisboa. The apartment was nicely and well furnished, it's access was very well explained. No keys to use. There was some coffee and tea and even a bottle of wine in the kitchen . But at first we couldn't find the bottle opener (because there was a hidden drawer :-))
Also a very good bed and no noise at all in the evening, so we slept well. I hope to come back soon. I loved the city with its beautiful colours and friendly people.
