We've been a week at Daniel apartment and the experience was perfect.
The location is really good, few blocks from Grand Central and you can walk to go most of NYC attractions. The apartment was clean, airy and light, with everything you can need. Even if is just one-space apartment it's not small, like the bathroom and you have three closets to use and enough space for your bags. The views are great and it's really quite.
I will recommend to everyone to stay there, it was a great experience.
