It’s an amazing spot right at the center of the city! The location is great, near to lots of restaurants, market, and several sightseeing places. The place is great for 6 persons, very well equipped, clean, lots of space with comfortable furniture, side view of the Praça do Comércio and the river, and we felt very safe. The reception was great and we didn’t have any trouble. The only thing I would point is the stairs, if you have problems going up and down 3 floors (but we handled it just fine).
Additionally, Samuel sent a PDF file with basic information and tips prior to our arrival and that was great! Most of the questions were answered there which facilitated our stay!
I totally recommend the place!
