We (2people) had a really nice stay at Gaspers place.
He himself was not in town but his housemaid Dona Fatima was there to let us inside the apartment and showed us everything important.
Though Gaspar was not in town he was always available via whatsapp and explained us one question with the shower which was solved very quick - so, even not in town, still a great host.
The apartment itself fulfills all basic needs and was in a perfect cleaned and tidied condition.
The view itself is like in the picture - amazing.
This place is in a very nice and not so touristic area located, called Flamengo. To the main touristic spots like Copacabana or Ipanema does it take around 30 Minutes, including walk to the metro.
The nice but at night a little bit dangerous neighborhood Lapa (relax but don't walk there with jewelry) is in a 15 minutes walking distance. All important museums are in the city centre and also in an acceptable walking distance.

If you want a modest place to stay and sleep with all basic needs, which is not in a touristic centre but still in a safe neighborhood, I would recommend the stay at Gaspars place.
