Four of us stayed for three days after Carnival at Diogo's place and I couldn't be more satisfied. The apartment is one block from the beach, it's small, but it's worth the price (way cheaper than a lot of the hostels I checked). The location is good, but we felt safer taking cabs at night rather than walking around the area. It's a one bedroom apartment (two beds), that was renovated a while ago and has everything you'll need for a quick stay. The air conditioner and the wifi work perfectly, and towels and sheets were provided.
We had a minor problem with the shower, which was quickly solved by Diogo. He was extremely helpful and kept in touch throughout our stay, making sure everything was working fine.
I would definitely stay there again and recommend it!!!
