My stay at Joao was great. It is conveniently located close to the metro and a 15 min walk to the old town. Joao was most helpful, before and during my stay. He had maps and loads of suggestions on sites not to miss, even recommendation for restaurants in the area. He kindly touched base during my stay to make sure all was well. I would highly recommend a stay with Joao, I booked based on others review and was not disappointed.
