Nice flat very well located in the center. The heater (was in winter...) and the wifi are working fine.
There is some noise from the surrounding bars and restaurants, but this is the price for be centric. Anyway, it is not all the night, so it is fine. Around the appartement our favorite place was the bar Metaforas.
We didn't met Cristina but it was very easy to communicate with her and she was very responsive.
