Mauro's apartment is in a very central location, maybe 10-15 minutes walk maximum to the Cathedral. Food and supermarkets are very close by, you can walk everywhere from here.
Mauro and Sharon were helpful and friendly. The room was large and the bed was comfy. Others have commented on the street noise, we didn't find it a problem except for when an emergency vehicle went past you could really hear the siren, but that doesn't happen enough to be of much concern. We found the room very hot as there is no air conditioning, but the fan in the room helps. Staying in August though I imagine anywhere without air conditioning will heat up.
We would stay again with no hesitation.
