Good hotel
we have visited NY many times and allways stayed in Hamptonn Inn chelsea (sister of the hilton brand) and located exactly 5 minutes downtown from the garden inn.
As this hotel also got good reviews we decided to try this one out.
Checkin was smooth and roomsize of for NY standards.Room was also clean and had a microwave, lots of tv channels and a mini fridge. In itself the hotel was good.
However reason why we will choose the hampton inn next time again are below
We did prefer the location of the hampton inn only for the subway options on 23rd street. The garden inn also has subway close by but not all lines. Second reason is the noise we experienced from other rooms which we have never encountered in any hotel. We could literaly hear conversations word for word from our neighbours. Third reason is the quite street which can be a bit seedy at night. 
Not bad but ont perfect as well.
