Anna and I stayed 2 weeks in this apartment, and it suited us very well. Enough space, and, important for us, it is a light apartment.
Jennifer and Helcio welcomed us in their (obviously natural) friendly manner, explained what needed to be explained, and let us enjoy our time.
We are happy we found this address.
Furthermore, Santa Helena is an excellent neighbourhood to stay, as long as you are physically fit: steep streets! Do not miss the museum in the same street, the Castro Maya collection.
