We just came back from what was a marvelous week in Ana's sweet little bundle of cool that is her studio in Ipanema. We were 4 adults staying there for the world cup and we enjoyed the quietness of the appartment despite the busy location.
Ana was very kind and warm to us both in check in and check out and the building was secure enough for us to leave our luggage in the lobby for a couple of hours when needed.
In general, the appartment is about 10 minutes away the nearest station and two blocks away from the lovely Ipanema beach, in one word, perfectly located. Also, the area felt safe at all times including at night.
