I stayed 3 1/2 weeks with Celeste and it was great! She is a really nice host and always gave me the information I needed. Her flat is nice, the room I stayed in was quite big and I could use everything in the kitchen, wash my laundry and I shared the bathroom with her.
We talked a lot, sometimes we ate together and we also went together to the Copacabana and Ipanema beach. I felt very secure and had much fun with her really cute dog. The street Celeste lives in is a main street, so sometimes it's noisy, but everything you need is right around the corner.
I highly recommend a stay with Celeste, she really is a very friendly person who is always ready to help!
