Me and a friend stayed in Ana's studio for 3 nights in April. It was really lovely, it was modern and functional (we loved the bikes) and very well located, just a short walk to Trindade (one of the main train stations). Unfortunately the studio was quite cold and we only had one small heater for the whole place, but Ana provided us with a few blankets. There was also quite a strong smell of damp/sewage coming from the bathroom. The apartment upstairs was having work done so there was a lot of noise and banging starting from around 8.30am (luckily we were up and having breakfast by then) and the wifi disappeared when they were doing this work.
