The apartment is very comfortable and very quiet, in an old building. The rooftop terrace is peaceful and has a terrific view of the city, including the castle. We enjoyed watching the many cats on the rooftops a few stories below the terrace.
It is in a nice residential neighborhood that does not seem excessively influenced by tourism, but is a reasonable walking distance to many worthwhile destinations.
Joao was very kind to wait for us to check in late as a result of a delayed British Airways flight. We were happy to find some nice provisions for us in the refrigerator.
I agree with previous comments that this is not a good option for those with mobility issues due to the flights of stairs from the street to the apartment, and the steep narrow staircase to the sleeping loft. However, we are in our mid-60s with no mobility issues, and had no trouble with any of the stairs.
We highly recommend Joao's apartment.
