Me and my friends stayed here for three nights during our visit in Lisbon. Before our arrival the communication was really good and we got very good instructions to get to the apartment. Duarte who checked us was super nice and gave us great tips for the city and we felt very welcome. However during the first two nights we had real difficulty to sleep because there was a very loud sound waking us up throughout the night. We were not sure if it was a cat or a baby or a bird but it kept making noise that could be heard very loudly to the bedroom. Another problem was that it looked like there was a humidity problem in the bedroom and possibly some mold or moisture on the wall. There was a dehumidifier in the apartment but it wasn't much help when it filled up about every 8 hours and wasn't taking enough humidity out the air. Even with these issues we had a lovely stay in Lisbon and the apartment was comfortable and clean and very well situated.
