My friend and I stayed at Aymerics for 1 week. The place was cosy charming with a stunning view of rio! There are two beds, one single in the lounge that doubles to a couch and the other in the bedroom on the floor.
Be aware though, if you and insects do not like each other, you could find a couple of little friends in bed with you or next to you walking besides the bed. Aymeric did advice me there's insect sprays under the kitchen sink. Ants are avoidable there but I did see the odd cockroach and two centipedes. But if you are fine with all that, you will have an amazing time there.
Location is beautiful, go for walk and explore the streets. In the morning try catch the monkeys up in the powerlines. Santa Teresa is a lovely area, and Lapa is around the corner so go check out the famous tiled stairs. You feel somewhat safe in the area but always be cautious of your surroundings. Beaches are approx. 20-25min train ride away. And you can catch a white kombi minibus to take you back home after your day out, just tell the driver the street name and it's better if you know Portuguese, it'll make things a lot easier. You'll find it located approx. 150 metres up from the train station (Gloria)
There are lots of stairs going up to the house, so if you have heavy luggage or lots of it, you may end up doing two trips. Once you are up there and you see the view, it's worth it! ;)
