It was our pleasure to stay at the Arturo's apartment, everything was great, the host was most welcoming and gave us lots of tips about restaurants and attractions. The roof garden is very nice. Location is very convenient, close to the port, near the Universita subway station. There is a good grocery store "Grangusto" nearby.
Be warned though that there is no elevator, and the building is pretty high, so if someone in your family has health problems it may become a challenge. Also there are two nice white cats living at the patio, people with allergy need be aware.
Overall very good experience, we really enjoyed it!
