My partner and I stayed here for 5 days. The building has a beautiful courtyard and the place itself has great lighting. Felt very safe and there is a cafe within the building. Very close to Mercado de San Juan and Bosforo bar.
The only real issue would be people walking on the skylight roof— sometimes at inconvenient times of the morning/night. Not much one can do but was woken up a few times during the stay.
