Mariza's studio apartment was exactly what I was looking for. The location was perfect being just 2 blocks from Copacabana beach and one block from the metro station. I was able to walk everywhere I wanted to go.
While Rio itself was very hot and humid, Mariza's studio was cool and temperature controlled with her wall mounted air conditioner. The shower was spacious and didnt get too foggy. The kitchen had everything you could need.
I did have a little trouble initially finding the place as it is located inside a small mall, but the door man quickly saw my bag and waved me down to give me the key.
Was fantastic for a single person and I am sure a couple would be just as fine.
