I stayed at Um Hostel last month and I liked it a lot. The hostel is very well located in Petrópolis downtown, in front of the Bohemia Brewery, next to the Imperial Museum, Crystal Palace and there are also good pubs nearby. The structure of the place is very new and quite modern. The decoration is amazing and so are the game room, the external area and bedrooms. I chose a shared bedroom they are cosy and comfortable besides spacious and well-equipped. The staff of the hostel are friendly and cool. The prices are very good, considering how good the place is. I really enjoyed my stay at Um Hostel and I hope to come back soon.
UM Hostel is a cool and affordable place to stay in Petropolis. The location cannot be better with Bohemia brewery on the other side of the river, Palacio de Cristal around the block and most of the city highlights on walking distance. The room was clean, the bed huge and the place is nice and cozy. The staff was nice and interested on help, but you may want to make a little bit of a better job on learning interesting tips about the city. To create a simple but informational manual for them to work as good concierges can give you that extra star. Breakfast was a little bit of "meh" because there was a lack of different fruit options (only papaya), sugarless yogurt and low fat milk. You cannot call yourself a contemporary hostel design if you don't have in mind little details like low fat milk, cheap good bread, more fruit options and those details for people who eat as different as the hotel wants to be. ;)
The accomodations are fantastic, the place is clean, the service is great. The common room is well equiped and cozzy. The location is great, just a block from the main square, near to everything you'll need. Simply one of the best hostels I've ever been
