Would stay again
Pros:

Size of the apartment, amenities (full kitchen, bathroom, laundry, and bedding supplies. Extra supplies are easily accessible, close to eating, grocery shopping and attractions.

Cons:

The unit was on the road side which was extremely active at all times of the day and night. Needed to use ear plugs (which were provided) for sleeping. The pull out couch bed was not very comfortable.

Beautiful apartment let down by poor design and property maintenance.
Pros:

Beautiful apartment shame it was let down by poor design and attention to detail.
It was easy to enter the apartment
The apartment was in a good location

Cons:

The noise levels from outside is horrific, it feels like there are paper walls.
The hearing/ AC system took all night to cool the room down.
The blinds in the bedroom did not fit one of the windows resulting in poor privacy and it being daylight in the room at 5am
The blinds in the lounge where the sofa bed is offer no privacy or light filtering at all.
One of the lamps in the bedroom was broken.
The bedding was ill fitting
The bathroom flooring requires attention. The ground was missing in parts resulting in sharp edges.

Pros:

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…

Pros:

My first time staying at a Sonder. The location was close to Temple University. Parking lot access right next door. Room was spacious and had all the amenities. My husband is handicap and in a wheelchair so I live chatted and asked for assistance and even though there is no on site help they sent Jonathan to help and he was great. Like your own little apartment. Only con was could hear person above us walking. Sounded like jolly green giant.

Pros:

I loved how you can walk to many places that has so much culture like love park, museums, and many good bars and restaurants. The view at nice is also a plus from the room and rooftop amazing. Also loved the privacy. What I didn’t like was the looked nice but had so many damages and black smudges on the white walls. Try to get room change and never received a response until the 2nd day I was there, mind you I was there for 3 days. Also had stains on the comforter and the extra one was ripped. I requested a new one didn’t happened until the next day. The elevator also had went out and they never gave a notice even though they say they did. So would I come back to this Sonder no I would not and would not recommend.

Nice but loud and unsecure entry to main hallway
Pros:

It would be ideal hotel for a solo trip with no kids.
No front counter or drive up area to unload luggage
Door to the lobby is very unsecure, questionable People in the hallway at times.
Rooms are very loud due to outside traffic.

Rooms were nice, probably would not stay there again.

Not this property
Pros:

Convenient parking next door, and clean apartment.

Cons:

This particular Sonder operates on codes not key fobs as others. The apartment unit code kept failing even though keying it correctly. My last night I spent over 10 minutes trying to get in, and the lack of having in building staff or custo.er service on the phone was a huge detriment. They did not advise prior to arrival of any needed repairs yet late night got an email of them coming at 8am arbitrarily. Had to spend time waiting on chat to address they could not come in at this time. These inconveniences will significantly impact me continuing to use these, as I've been using these facilities for many years now.
