The ONLY reason to buy this is if you want to use it in NYC. The MF are quite high, especially being a gold week. We own at W 57th St (platinum weeks) but usually go during gold season to stretch our points. Gold season is cold (Jan/Feb) and hot (July/August). However, I've gone in March when it's freeing and in June when it's roasting - so YMMV. We feel the gold weeks are fine.
The 1 bedroom penthouse units at the Residences are quite nice. They are on the top 2 floors which only have 6 or 8 units each so feel very private. There is a separate elevator from the main floor of the Residences to those 2 floors so it's easy to access. It's also on the end with the owner's lounge so you don't have to go the length of the long hallway.
The Residences has daily housekeeping included. A couple of the penthouses have amazing views (but some look to other buildings).
They have electronic blinds and the bathroom has heated floors (nice in winter). Ironically, because they have a door to the bathroom from both the bedroom and the living room, the sink and vanity are relatively small. Lots of marble in the bathroom.
The other factor is being part of the Hilton Hotel. That means wading through the masses in the main lobby and waiting on the elevators.
It also means you get nickled and dimed. Need to check a bag - $5 each. Need to receive a package - $5 to $10. Need to use a computer - there is a charge. There are no fees like that at W 5th St.
IF you want to go to New York, it's a lovely place to stay. I'm sure it wouldn't be hard to spend $500 per night or more for similar accommodations.
