Gustavo's place was just right for my stay in Lisbon. It's an easy walk from the metro and there are ample shops nearby for anything you may need. Even currency exchange is only 4 blocks away.
Although I only saw Gustavo once briefly during my stay, he sat down with me and pointed out all of the best locations to visit.
Gustavo's roommates were fantastic! They went above and beyond to make sure I felt very welcome and that my stay was comfortable, even inviting me along on their outings. They took the time to point out interesting places in the city and explain the history too. What a great place to stay with so many nice people! I would highly recommend it.
