Dear Rosalia and Paolo,
You are great hosts, and provide valuable advice on what to see, where to buy and what to eat (esp. as we were vegetarians). It was great to have you available right at the apartment.
The location of the apartment is slight far from the description, but that is something one cannot really visualise till one walks in the city.
You did allow us to check in at 2pm instead of 3 pm, but since you stay at the apartment, maybe you could accommodate dropping off baggage, (the cost of baggage locker is much higher than bus charges to reach your place from SNM station).
Loved being there, room is spacious as seen in photos, and loved Rosalia's suggestions on where to eat and what, especially Zaza.. And conversation with Paolo was great...
