We stayed here for more than two weeks. The set-up is great for longer-term, since you get your own cooking and laundry facilities inside your room/apartment: but housekeeping and cleaning is 100% on you in that period. They will give you basic supplies eg more toilet paper and garbage bags. They’re also really nice on reception.
The building is very clean and in good condition, although the halls on the floors where the apartments are feel depressing, with poor lighting and peeling paint. We were super worried when we stepped out of the elevator to walk down to our room, but the rooms themselves were terrific. Clean, well-equipped, and a good amount of storage space. The kitchen and all the appliances and utensils were in excellent condition.
The biggest drawbacks were - in the following order:
1) thin walls, as other reviewers have commented - Mostly we were lucky. But then there was the drunken couple getting it on, the kids playing K-Pop Demons Hunters at 4am, the party girls, etc. And …
2) … at night, there is noone on reception and no easy way to contact anyone directly for help.
3) The area is a bit sketchy. Philly has much worse but it also has much better. You’re going to see a lot of people sleeping on sidewalks around the Convention Center area and some of them are really not ok.
I loved the concept and the friendly staff, but not the on and off noisiness. Might stay again but not sure.
