Look no further....
My wife and I were 4 nights in Paulo's studio and we couldn't of been more pleased. To be honest, we came across Paulo's place because another host cancelled out on us at the last minute, and during our entire stay we kept saying how lucky we were that ended up at Paulo's studio. Perfect location, spotless, bright, flawless internet, exactly as described - perfect for a couple. The bed is extremely comfortable (I sometimes have back problems) and we both slept like a charm!
Yes, it is a five story walk up and some of the stairs are steep, but to us it only added to the charm of the building and was part of the experience - loved it!
Paulo was a perfect host: seamless communications, met us a check in / check out, followed up with us during our stay and provided us great with great, insider suggestions (like the classic Ginjinha establishment next door - a must during your stay)
If you are looking for a large studio in a clutch location then we would highly recommend Paulo's studio.
