Our group of 4, (2couples) had a great experience here and always felt safe in Euler's apartment. Doorman on duty 24hrs and the gate is always closed/locked.
From the photos, I expected a very clean and modern property, realistically slightly dated (but true to photos), smaller than expected but comfortable for (no more than) 2 couples/4 very good friends.
Convieniently located - walking distance to Ipanema beach, lagoa and main street with shops, grocery stores and pharmacy. Taxis always available at the closest intersection.
Internet wifi connection not always reliable and does not reach the 2nd bedroom and kitchen.
functional air conditioning available in all bedrooms and living room.
Many towels and sheets at your disposal.
Kitchen pots/pans, utensils, plates and glassware are all available. Although mostly worn out, they are functional and usable.
We never met our host, but he was extremely reachable by e-mail and WhatsApp and accommodating to our requests.
Overall, I would recommend Euler's apartment for any couple, small group of friends or small family for a stay under 1 week.
