Luis was quickly responsive to my spontaneous request. I met him at the building for the key and some practical information. He was very welcoming. The studio flat was airy and spacious. I was staying alone but the studio would also be perfect for a couple or three people even. The building was securely gated with 24/7 doorman. The building was at the beginning of a street leading to a favela but the area around the building seemed safe enough with a couple of policemen standing just in front of the building every evening. The building is close to metro (3mins walk), supermarkets, restaurants, beaches. The location is great. The only con would be that the street in front of the building to which the studio is facing is a busy one. So it can be quite noisy during the day. Luis was a great host. He was very accommodating. He even let me stay until late in the afternoon because my flight was a late one in the evening.
