My friend and I stayed at Celia's place for 5 nights. As soon as we arrived we felt like home. The area of the apartment is very safe and is only 4 blocks from Ipanema beach which is very convenient. Its also very close from the metro station from where you can go to the center. Celia takes time to explain you all you have to know about Rio and where to go. The room and the private bathroom are spotless which we really appreciated. You also have big closets to store your luggage. Even though she didn't have to, she offered us breakfast everyday with nice fresh fruits.
We enjoyed to stay at Celia's place very much and we would definitely come back.
