Top Great Diamond Island Hotel Reviews

The Westin Portland Harborview

10/10 Excellent

"We really liked the Westin property. We were able to check in early which made it so helpful. Room was very clean and ready. Breakfast was fantastic. I loved that there was a Peloton bike in good working order in the workout room. If we go back to Portland I would stay there again."

Portland Regency Hotel & Spa

10/10 Excellent

"Visited Portland for the first time, the Regency is in the perfect location. It’s a great food town, do your homework before you go and make reservations."
