Carla's apartment is well renovated and in a smart area close to everything for sightseeing. There is a 24 hour concierge. Carla's friend made us feel welcome and showed us around the apartment. The apartment is fairly well fitted out but lacked any coffee making facility although there was coffee in the cupboard. The bed had a plastic sheet over it which was not comfortable and needed some higher pillows.
We tried to communicate with Carla's friend via text but this was not successful.
The apartment was fairly quiet on each night except Saturday. We slept with the windows closed.
