I would not stay here again.
Hotel Pennsylvania is a very large hotel with a nice main hall at the entrance and It's a great location, but overall It is dull and the rooms are quite shabby and not very clean, strange cracks and 'stains' on the walls, floors and ceiling, very very basic.
When you're in New York you are barely in your hotel room as you're so busy out doing all different things, however It's nice to come back to a nice, clean environment at the end of a tiring day and I would not recommend this hotel.
Although we did not experience any bed bugs, I recently heard this hotel is at ranking #1 for most bed bugs ridden hotel in New York.. yikes!
We are returning to New York next month but we are not be staying here again, a lot of refurbishment needed!
