We had a wonderful time at Emily's apartment. She was very forthcoming and checked up on us via WhatsApp often. We needed some very specific things at a certain time and she proved very helpful.
The apartment was wonderful and cozy. We stayed quite a while and the combination couch + netflix was welcome evening entertainment after a long day sightseeing in cold NYC. The apartment building is old (and could use some upkeep), so there might be strange sounds that you can't place. The bathroom was really small, but the water was warm. The bed was comfortable the first 3 days. After that the feather pillows proved too little support for those necks and shoulders that need it.
The neighbourhood, Williamsburg, was wonderful. There were plenty of cute book stores, cheese shops, jewellers and junk stores side by side, though definitely on the pricey range of things. Lots of places to eat and not too far from 2 subway lines and a ferry and you're in Manhattan in a jiffy. We were happy to relax here and leave the hustle and bustle of Manhattan.
