We stayed in this apartment for one week and it was a perfect location for us. It is a short walk to a train and metro station and there are several restaurants, mini-markets and bars in the area. It is located in a quiet area with only pedestrian traffic, but taxis stop just a few meters from the apartment.
Maria and Filipe were wonderful hosts and provided a map with personal suggestions for restaurants, museums, unique shopping, and more. They have done an amazing job restoring and redesigning the apartment space. The building is obviously a labor of love and a unique and very livable space for two people. There is a mobile phone for renters' use which has their numbers and taxi number programmed in. We carried it with us while we were there. We used it to call a taxi for our trip to the airport at 2:30 in the morning which was super handy.
The apartment has fans for cooling and air movement which we needed for sleeping. It is on the ground floor, so we did not open the window at night, even though the immediate neighborhood is safe and residential. There are two small air vents that open in the bathroom and the sleeping alcove and they helped somewhat. We would happily stay there again, but not in the hottest months unless there was air-conditioning.
Overall, a comfortable stay with great hosts in our favorite part of Lisbon.
