We really enjoyed our stay at Sofia's apartment. It was in a great location in Mouraria and is within walking distance of all major sights to see in the city, which was very convenient. She gave us fantastic local recommendations on places to eat, which we would have never found on trip advisor! Though the apartment didn't have air conditioning, this didn't really bother us. You have to walk down a set of stairs to get to the apartment (as you do to get to most old buildings in Lisbon), which didn't bother us, but just a note if you have trouble with stairs or carrying extremely heavy baggage. Would recommend this apartment for sure!
