Clean and thoughtful
Great hotel. Very clean and convenient. Appreciated the comp. late check-out due to the Portland Marathon event that morning. Convenient valet parking.

Very Good 8.0
Great Location for Feast! Portland
Great location, quiet room; clean when I checked in. No cleaning service offered 2nd day. No accessible bathroom at the lobby - the bathroom for that area (which also serviced the bar/lounge area) was down a flight of stairs, so as a person with mobility issues (I use a cane) it was tough to navigate.

This hotel is at the hart of downtown Portland by Pioneer Square. It is located at convenient location for shopping, parking, restaurants. Valet parking is $46 per day with unlimited in and outs. But there is Smart Parking across the street which is $21 per day. You do not need to take a car to get around by walking or taking a street car/bus. If you park this garage after 5pm, overnight parking is only $5. Very clean and quiet room. Nice spacious bathroom with a walk in shower. No tub. Check in is 4pm but I was able to check in a bit early. It is nice to have a check out time of noon!!! I would recommend this hotel highly.

AC Marriott. Good choice!
Excellent location, rooms are clean and comfortable and the Wi-Fi was great. One downfall is this setup for drop-offs and pickups for shuttles, tours, Ubers ; Its not at all accommodating for that. Aside from that I would stay here again.
