We stayed here a second time because the Pope was in town and there was no other venue to stay in (the first time was one day, Labor Day). We left a day early because we were lucky enough to be given tickets to see the Pope and had free accommodations in the city. We have been staying in the surrounding areas for the past month in almost every Airbnb facility that was available. All I can say is, if you can break the bank and add $15 per night, you can get a whole apartment in a high end area through Airbnb with quality beds, furnishings, luxury towels, sheets (fully equipped kitchen in most cases), cleanliness AND privacy. You will also get a well traveled loving host that can either take care of you or leave you alone if you desire. Not a host that is judgmental and pasting rules all over the walls- we expected some Brazilian easygoing feeling but we got the "Newark" experience instead.
There are no locks in any of the rooms (not bathroom either); All doors are open and there is a disturbing alarm that goes of at 10 am every morning from his room - needless to say this place is for the traveler that wants to pay little, that is used to staying in hostels, and gets out first thing in the morning and comes back late. The train station is far away, you will need UBER, taxi, or the host to give you a ride.
