Adriana's location is EXCELLENT. I stayed at another place near Trindade and I prefered closer to the river much better. The ONLY complaint I had was the mattress was very thin on the bed. I ended up sleeping on the sofabed which I thought was better. Also, there are 3 keys to access 3 different doors which must remained unlocked. As there were 2 of us, it meant we had to always come/go together. As there is a middle door, we couldn't even leave without one person walking down with the keys.
Otherwise, I think this is an excellent location. It was clean and comfortable. It was fairly quiet. The communication with Adriana was quick and efficient. The views from the cute and large terrace were wonderful. I stayed 4 nights and was very happy. I highly recommend staying here!
