Me and my friend stayed 4 nights. We had a very nice room, with our own balcony. The communication with Belem was very fast and easy. At arrival she showed us around and gave nice sightseeing tips. We had a perfekt stay and nothing to complain. Just one thing to mention: the front door is noisy and you can hear the other visitors in their rooms. However, our appartmentmates where quite respectful and silent when arriving late at night.
Therefore I can highly recommend to stay with Belem. :)
