I want to say that I booked at the last minute and was worried about the place I would get. Luckily Guilherme was my host and he took excellent care of me going beyond simply providing room and board. He completely went out of his way to help me plan the second....completely unplanned.....part of my trip helping me make hotel and travel arrangements to Ihla Grande (which you must absolutely see if you visit Brazil). I cannot over state how helpful Guilherme was. Now about the apartment, it was a studio layout that was separate from his side of the apartment but still provided a spot for me to leave my items without fear of leaving anything out. The building was secure and very close to the beach. It was clean and Guilherme provided all the basics needed for a pleasant stay.
There are a few cons, across the street a museum is being built so sleeping in is not going to happen until that's complete, I went during the world cup so the streets were loud at night, it's not a five star hotel.... but if that's what you're looking for then why bother going to Rio?
You will be happy here and Guilherme will make your stay excellent and worth every penny.
