I've stayed at Euler's apartment with my family of 5 in July 2017 and loved the experience! The apartment is in a very residential and quiet area in Ipanema (10 minutes to the beach), you can walk everywhere and it's easy to take uber to pretty much any place. The apartment is just lovely: spacious, super clean, and with an awesome balcony where we had our breakfast every morning. Euler is an amazing host and was very gracious, responsive and willing to help with anything. The beds/linens are extremely comfortable and the kitchen is well equipped. I would certainly stay here again and would strongly recommend this place in a heart beat!
