My wife and I's stay at Mareclo and Miriam place was great. The apartment is just as described and perfectly located for the short walk to Leme beach, restaurants, pharmacy and grocery stores, but with the benefit of a calmness which Copacabana does not have all the time.
The biggest benefit of our stay was having Marcel and Miriam as hosts. They were very kind and helpful. The gave us plenty of tips (including leaflets) and advice on what to do, places to eat and were always available if we needed anything (they were so kind to even send us a WhatsApp message to check that we had settled in okay). On top of that they even had a caipirinha kit set up for us on arrival, so we could attempt our own versions of the national drink (a very nice touch indeed).
Mareclo and Mariam thank you thank much for letting us stay at your apartment!
