We had a great stay in Mario's apartment. Even though we didn't meet him personally, Mario is an excellent host and a super communicator, every efficient and quick in response to our questions or requests. The place is in a great location, very convenient for travelling to airport or anywhere by metro & train. The apartment is also located in a a very lively area, a lot of restaurants and great food. The studio is very spacious and bright, everything just like the photos show. The bed is the best we had for our whole trip in Portugal. Mario also provided us a very useful personal map, and we just followed it and visited the places & restaurants he recommended. One bonus of this stay is the free breakfast at the cafe"The World needs Nata", it was simple but good! All in all we have an excellent stay in Mario's place.
