Perfectly situated, impeccably clean, and generously spacious. The convenience of having parking right next door makes it even better.

I came to Philly for a conference. This is a perfect 10 minute walk away from the convention center and also very close to many attractions downtown.

Fantastic location
The apartment was beautiful and within easy walking distance of everything. The view was spectacular. The terrace would be lovely when the weather is warmer. I am already planning another trip. There are only 2 things to be aware of: 1) unloading luggage is challenging, there isn't really a good place to park 2) be aware that the main bed is a double and not a queen.

A prefect stay, I will definitely stay here again if I am coming back to Philadelphia. A very good location, fitness and rooftop made the stay extra good. Everything I needed and more. ❤️

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.

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.

The room was very noisy due to the traffic. I understand now why noise canceling ear buds were visible in the room.

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!

Liked: Room comfort
Nice place to stay. Just super loud and noisy. Not sure we would stay again just because of the noise.

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.
