The apartment was very nice in overall, we had almost all we need, and conditions were quite good. Very nice location, not so far from city center. Public transport quite close, bus connecting to central station right there, and metro stops at less than 800m, connecting to everywhere.
Couple of things to mention, for future guests to have in mind and for host to improve:
If you will stay for several days (10 days in our case), notice that no cleaning nor towels changing in-between was done.
Communication was weak. Donato was quick in our first contact with him, but it was not the case with the person he left in charge. Too delayed answers (when he did) and not as detailed as we needed in most cases.
Anyway, we had a nice stay in overall. We recommend this apartment, if you take into account all stated above.
