We enjoyed our stay in Clarissa's and Bradley's apartment. Instructions to get in were very easy and apartment looked as beautiful as in photos. The view from terrace far exceeded my imagination and I have many photos of the view to Manhattan. The stairs that we were warned very just a good exercise for us. We enjoyed our weekend in Brooklyn and big part of that was the beautiful place we stayed.
PS. This did not bother us, but in April 2015, L train does not work on weekends.
PS2. We highly recommend this apartment and could consider coming back.
