We had a great stay at Pedro's. The studio is very well located and close to everything you'd need in the city. It was literally a 10-minute walk to any of the major attractions in downtown Lisbon. The only place that is a bit far is Belém, but you can take the tram stop is just around the corner. It has all you need for a short vacation!
Pedro is also a very communicative and proactive host, who welcomed us, answered all our questions about what to do/ where to go and kept in touch during our stay to make sure everything was all right.
We'll stay there again when we visit Lisbon the next time.
