We enjoyed our stay at Maria’s place. It Is compact but very well organized. Super clean. Very central to the old town - you can walk to many sites or to public transportation easily. You felt like you were living among the local folks. Maria was very helpful, quick to reply and was very honest about her description of her place ( stairs might be an issue for older or younger guests; heritage district so neither taxi nor Uber could come right to the door but they did get us to within a short block of the flat so no problem to walk the last little bit). Maria had a great guest book with lots of suggestions for restaurants etc. She also left out some food basics which was very sweet of her but we didn’t end up using them because there was a grocery store and lots of places to buy fresh stuff nearby. Overall would highly recommend if you are looking for a place that will enable you to have an authentic base from which to explore historic Lisbon.
