Quiet location, beautiful and modern decor. Windows floor to ceiling brings lots of light and a great view. The only bad thing I can say is that you can hear everything from next room…

Great value for Philly city center.

Very happy with this aparthotel, just on the outskirts of the city center, good location for a lot of major attractions. Nearby parking was a breeze. Apartment was nicely furnished and in good condition. Very clean. Would be happy to return.
