Beautiful room!! Brand new, full kitchen. Exceeded my expectations. Great location!! Restaurants, bars are all in walking distance. We’ll definitely be back!!
We loved staying here! Loved that it had a full kitchen, and the location was perfect! We could park the car and then not have to worry about having to drive around. We stayed in town to enjoy the Prescott Park's outdoor theater (within' walking distance) and was easily able walk around to find places to eat or shop around. We also loved the rooftop table and seating area. When we are in the area we will be back!
New hotel right downtown. Good location to the Music Hall. Also has an underground parking garage

Beautiful historic hotel in a fantastic location. The rooms are spacious, clean, and new. We had a full kitchen suite and a very large bathroom. The setup is atypical in that there is no staff onsite. This really is not a problem so long as you know not to expect a traditional hotel staff. My only complaint is that the technology used for checking in remotely is not good. I had to attempt checking multiple times and the way check in information is communicated is not streamlined. This is a minor grievance considering the bang for your buck you get in staying at the Treadwell. There is room for improvement for the check in process. Regardless of this, I highly recommend staying here over other hotels.

Disliked: Check-in, communication
Rooms and general areas are VERY NICE. However, you cannot get into the building or the parking cave without the 5 digit code they send you. But not until 3:30!!! Your code will not let you in until that time AND THERE IS NO DESK OR HOST IN THE BUILDING to let you in or talk to. Also be aware that the parking cave has a very tight turn at the entrance that would likely not be possible with anything bigger than a standard car, and local street parking is nearly impossible. Stay was really nice once we were actually allowed in the building and parking cave, and the location is in the middle of lots of shops and restaurants.
Positives: comfy memory foam bed, clean space, nice location. The rooms are in a converted historic building, and while many interior features are attractive, the project seems very rushed, and a lot of important items are missing or poorly done (especially to be a four star as they claim)
Most importantly, the AI model is a hellish experience. The communications pretend to come from a real person but are coming from a computer. The AI ("concierge") will waste 30 minutes of your time going round and round on any request before maybe escalating to a real human. The human then chooses responses from an AI menu. It's absolutely awful. The AI sends many many pre-scheduled messages and responds with insulting platitudes that don;t help at all. One night I watched three different frustrated parties unable to get into their rooms and the garage. One woman didn't;t know she was communicating via text with a computer.
Also:
1. No decent coffee. There are a lot of Keurig pods, but they are gross. There is no drip maker, French press, or Nespresso. 4 star?
2. No full length mirror- just a small bathroom vanity mirror
3. Plastic disposable cups in bath, as in Motel 6
4. unlabeled and unidentifiable shower toiletries (is it shampoo, conditioner, soap?)
5. A thermostat that is externally controlled (you can move it a few degrees up or down- that's it.) Our room was freezing, and despite asking many times, we could not turn the AC off.
6. No bathrobes/slippers
7. No bowls in kitchen
we loved our room and the hotel! it was perfect for our frost wedding anniversary and trip to portsmouth. super easy and quick check in the hotel was safe and secure, plus the beds were soo comfortable! Highly recommend! no complaints :)
