Carlos's flat is super nice, located centrally in Roma Norte. It is on the ground floor of an old house (mansion really) with a wall of glass doors looking out on a lovely garden. Garden is a shared space with one other ground level apartment, Carlos's family, who live on the second level, and 3 cats. The place is roomy and pretty quiet for the center of the city. The biggest plus for me was the high end kitchen as I was there for a while and did quite a bit of my own cooking.
