Ana's place is as described. It have a wonderful view of Christ the Redeemer on a clear day. The breakfast is amazing, really get you ready for the day. It is in a residential area so it is pretty safe. There is a bus out front that will take you into town that comes frequently.
P.s. if you are coming for Carnaval please be aware that there are lots of road closure and Santa Teresa is an area that will be effected. We had lots of difficulty finding taxi that will take us there at certain times.
