We had a lovely stay at Rita and Miguel's apartment - Miguel greeted us for the check-in and walked us through the apartment. The steps up to the apartment are VERY steep and narrow so we were glad to have small luggage to carry up and down the stairs. There's construction going on next door that started around 8am that was a bit loud but is only temporary.
The location is very central to some major areas of Lisbon, often only 10-20 minutes of walking to major landmarks.
We found the bed soft and slightly firm but comfortable and were very thankful for the air condition. They provided us with a bottle of water and many recommendations for restaurants, sites, grocery stores, etc. which was great.
We really enjoyed our stay here and would recommend it!
