I wanted to see Serra da Dos Orgaos park near Petropolis and there didnt seem to be many hotels in the area, so I thought it better to book a hotel in advance before leaving the US. I didnt know what to expect from this hotel, but I was pleasantly surprised. Lots of old artifacts and art work all around this hotel. The staff was friendly and helpful and spoke enough English for me to communicate.
This was a 'garden-style' hotel, and altho it was an older hotel, it was well maintained. In front of the hotel, there's a little park-like area, and there I saw the biggest pine cones I've ever seen (if that is what they were). My room was comfortable and easily big enough for 1 person and had a TV. No AC that I could find in my room, but didnt really need it since it is in the mountains and not too hot. It had a pool and I think it also had a workout room. The continental breakfast was nice and had a nice selection of items, as I found to be the case in most of the hotels in Brazil. They also served dinner for about 23 Reals more, I think, but I didnt partake.
The hotel was a little hard to find if you dont understand Portuguese, and street signs seemed almost non-existent, so the fact that I knew the road the hotel was on didnt help. I found it by accident after wandering around for a while (a sign on the road indicated the hotel), but after I found out where it was, it was pretty easy to find again. And not much room for parking; only 4-5 'official' spaces, altho there were a few more 'unofficial' ones. But mine was one of only a handful of cars and it wasnt a problem.
That said, I found that the place to stay if you want to see the popular features of Dos Orgaos park (Dedo de Deus, etc.) is in Teresopolis. These are actually a good ways from Petropolis; took me probably the better part of 2 hours to get there. You can see these from the highway traveling from Rio to Teresopolis, so you really dont even have to spend the night up there (altho you might want to as a break from the congestion and heat of Rio in the summertime). But if you also want to see the museums of Petropolis, this hotel is a good, moderate-cost option. My price was 148 Reals, I think, which was about $82. And I just saw a price of $63 on this site.
All things considered, including the money, I'd have to say that (along w the Quality Inn in Curitiba) it was about the best hotel I stayed in in my 9 days in Brazil.
