I had a very good experience being hosted by Lola. We happened to share some interests and thus we shared some talk over tea sometimes, which was nice. She was also helpful enough to accommodate to my flight schedule, and to give some recommendations on sightseeing on the neighborhood and beyond.
The apartment is exactly as described, I had no problem at all entering or leaving the building at any time. You can walk to a lot of places, jog besides the river or in some parks nearby, also lots of subways/buses around, I felt very safe.
