What else can I say ?
Ronald and I lived real "buddy" moments in we sometimes watched TV shows together when back from my trips in NYC.
His apartment is comfy and warm, the room is big. I really enjoyed the view on Soundview Park at mornings.
Ronald is available for picking you up and bringing you at the airport, just bring cash to pay tolls.
Nobody bothered me in the Bronx, there were old ladies blessing me and even guys cheering me for bringing beer at home :)
I found real Italians in Bronx Little Italy, which I reached in 40 minutes by bus, speaking Italian and telling me their stories. You will find a lot of Spanish speakers ad well, so life will be easy as a tourist.
Consider have a tour of Northern Bronx, you will find awesome natural parks.
Only downside is that corridor in the building had a strong weird smell that make me feel bad when I was leaving the apartment, but that's not Ronald's fault.
