Very modern vibe. Which was confusing b/c there were no USB or USB-C ports to charge your phone(s). The dishwasher was broken and the coffee grounds were expired.

I was expecting a more equipped kitchen. The knives are partially damaged. The microwave is awkwardly positioned; hard to reach. The dishwasher was inoperable; had stagnant water in it. Chairs and the kitchen table did not look clean. Shower stall in the bathroom is too narrow. Position of the soap bottles on the side wall make the shower stall effectively narrower. It is inconvenient to reach the handle and open the water tap without cold water falling on you as the showerhead is vertically positioned right above. All in all, I was expecting somewhat better for the price tag.

We stayed at a one bed room apartment for a week and totally enjoyed it. The apartment is new, well decorated and clean; there is a small but nice gym on the basement. The neighborhood is a little noisy from the street traffic at night (the windows could use a bit better insulation). Not too many restaurants or shops in the immediate surrounding but we had no problem using Uber to get around. Overall, we really liked it.

Wonderful location and amazingly decorated. Only concern is that on-site staff were not quick to fix issues with the unit's facilities, though support employees were great with addressing problems. Otherwise, definitely recommend if you're staying in Philly!

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.

Brand new building was clean and very elegant. Some things of note, the combination washer dryer went absolutely insane while washing a tiny load of laundry. Was aggressively shaking and flopping around and sounded like a jackhammer. Sorry to any of my neighbors that thought I was trying to break the wall down. Also the bathroom faucet was loose and literally falling over into the sink like it was on a hose and the coffee maker had the last guests brewed coffee and coffee grounds in it. Other than that it was a great stay

Good value for the money. One bedroom with living room and very well stocked kitchen. The rooms were somewhat noisy and our dryer and one bed lamp did not work. We asked for extra pillows which arrived the next day. This is sort of the Uber of hotels. No front desk. You enter the property and your unit with an access code.
