We spent almost three weeks in Eduardo's apartment and can totally recommend it for both long and short stay. What we appreciated most: the appartment is spacious and has just AMAZING Lagoa view; the area is beautiful and super safe, there's a nice nature park just beside the condo and several nice restaurants near the lake, easy acces to beaches (around 30 min of nice walk to Ipanema). And last, but not the least: Eduardo is very friendly and fullfilled all our requests.
What you sould be prepared for: the furniture and the amenities are functional but not completely new. There are no supermarkets near the apartment, you may use delivery or Uber for buying groceries. There is a busy road near the condo, so during the day you will hear the noise in the apartment.
Overall we had a wonderfull stay in the apartment and in Rio and will definately return again. Eduardo, thank you very much!
