We had a wonderful time and stay. The location was great in LoHi near restaurants, breweries, etc. They were able to help us out and checked in a few hours early for a very small fee. We were able to walk to the city (Union Station Convention Center, Parks etc) The room was a studio. Clean!!! No bugs! Bed was comfortable, clean shower with decent water pressure, kitchenette with dishwasher, and a washer/dryer in one. It was like a hotel...toiletries were available, you didn't have to do any cleanup prior to leaving. The Sonder building had multiple rooms, secure access into the building and secure code for the room itself.
We had some minor issues but this is being picky and would stay tlat the Sonder again if we visit Denver again. The window A/C unit worked but the fan on the unit made a really annoying sound that we couldn't shut off so we opened a window which worked out well. Parking was on-site but not enough for the whole building but street parking was free in that area. We used the washer/dryer in one but the dryer was incredibly loud as if it would explode and it was at night so we used a laundromat to dry our clothes which were super cheap and easy the next morning. The ceiling walls were thin as we heard the neighbors but never heard our next door neighbors.
Despite the minor issues we had, we would love to stay at this location again as the area was great, free parking, close to activities and food/drinks, 20ish minutes to the airport, near the highway, and easy walk into the downtown area.
