Thanks for letting us to stay! The flat is very central, the hosts are lovely, the flat is well designed.
However, there are a few things such as no A/C (which means it gets hot at night even with the fans provided), stair-only entrance which can make it tricky getting luggage upstairs, and the surrounding area at night (Centro Historico) that feels slightly unsafe (nothing specific to the flat which is VERY secure!).
The building itself is beautiful inside and you do stay in an important building which is really great. Overall we had a nice stay!
