I booked a double room for $ 80 at Luiz. He decided he would give me a single room for the same price. The pictures he sent me didn't correspond with the actual room. The house holds 3 guest rooms on the 3 floor and there's a tiny room without windows where Luiz sister sleeps. Because of the missing windows, the door is kept open at night - an interesting olfactory experience.
The other rooms weren't rented when I was there.. luckily. They all share the same bath room on the floor. I've stayed 5 days and met Luiz only the last night before I left in order to organise the key return. During my stay the bathroom got cleaned once.
The house has an advantage of having a great location. Literally 5 minutes walk to Ipanema Posto 9.
