We were visiting Lisbon at the end of September and stayed at Mario's appartment. Everything was great! We arrived late, there were snacks and wine for us, and Mario gave us a map of Lisbon with all the sights, food poins and other usefull information, and explained everything on that map! So we were very exciting and anticipating to see everything in Lisbon :)
The appartment was light, clean and very lovely, we had everything we needed.
The location was good, metro Rato is nearby and also a good cafe and a big supermarket. Not far from central part of Lisbon, safe and quite.
Me and my friends who were visiting Lisbon with me would recommend Mario's appartment to everyone!
