We spent 5 nights in Joao's nicely decorated and very bright apartment. We had no problems checking in as Joao was already there waiting for us. Joao was a great host and had no issues with communication as he usually responds within a few hours. There is a small terrace on the second floor of the apartment where we enjoyed breakfast. The apartment is located by the castle so it's busy during the day but very quiet at night (we didn't hear any fado music). The mattress is super comfortable! We slept like babies despite being so jet-lagged. Only issue we encountered was that we arrived in Lisbon at the tail end of a heat wave where temps reached 35+ degrees C and without any air-con or fan so the apartment did get sweltering hot. Nonetheless, Joao was kind enough to bring us a fan on the 3rd day which helped a lot! Overall, we had a pleasant stay at Joao's apartment and would recommend it to anyone looking to stay in a quaint and quiet area (but be ready for the trek everyday as it's up by the castle)!
