The location of this loft is ideal and definitely makes up for the noise that does permeate into the apartment from the trains. I didn't find the noise to be a huge issue, especially since there's a white noise machine by the bed that helps drown it out.
The only real problem I had while at the loft was that I couldn't for the life of me get the darn lock box to close back up, but thankfully Cindy was very understanding of this and allowed me to leave it inside when I left.
