My mom and I stayed in João's place, and it was perfect for us. It was clean, we had the option to separate the beds, and super secure/safe. The location was great and within walking distance to most of the main sights and neighborhoods in Lisbon (I think we only had to use Uber once or twice during our stay). João was a great host and was very communicative and helpful at check-in. Would definitely stay in João's place again the next time I come to Lisbon!
