Yes, this apartment is small, very small. I would only recommend it to people traveling alone, or couples who don't mind being very intimate with each other. Also: if you're planning on cooking a three-course meal every night this is not the place for you.
Fortunately the apartment is located centrally in Lapa, one of the most lively neighborhoods in Rio, with cheap restaurants literally on every corner, lots of bars and clubs, live music everywhere, and every Friday and Saturday a big street party.
The famous Lapa arches are just a stones' throw away, as is beautiful Santa Teresa, of which the apartments' only window gives a lovely view.
Bus and metro lines to beaches and all other attractions are near.
You'll get the drift by now: you won't spend much time staying in anyway.
Not that that would be a punishment though: small as it is the apartment is comfortable enough, with good air conditioning, tv and fast (wifi) internet connection.
The mezanine bed is cute, romantic and comfortable enough.
Also important in a noisy city like Rio: there is not too much noise coming from the street.
The apartment was spotlessly clean, and everything you need for a comfortable stay was there.
Fabiana and Barbara obviously take pride in being good hosts and offering a great experience. All appointments where meticulously kept, and they helped out wherever they could.
All in all my stay here was extremely pleasurable, very good value and I will certainly be coming back.
