I stayed in the Affinia 50 last year and would recommend it. One bedroom with bathroom and kitchen. Location is good - East 50th street, and the price was ok also.
Affinia Manhattan - just across from Penn station...a few blocks from Macys..location was excellent.
I got a 1 bed suite too as travelled with my dad.
Large sitting area with pull out bed, kitchen (with crockery etc) large double bedroom and a bathroom...only thing is you have to go through the bedrm to get to bathroom but this didn't bother me at all. Very modern and clean. Staff were lovely too.
