My stay at Federico's was cool: fantastic location and stylish place. I enjoyed the time!
Federico was quick and helpful in responses, check in and check out were super smooth.
I personally had two issues:
The heating makes air very warm and dry on the top floor (in the bed), while it's still very cold to stay in normal clothes downstairs. I found some balance, but it wasn't ideal. If you're more sensitive to it like me, keep it in mind for a winter stay.
While the courtyard is very quiet indeed, the heating system produces noise significantly more than a fridge - my expected noise level for a studio. It's still just an annoyance, didn't really disturb me after I fell asleep.
