Doubletree by Hilton Hotels in Windsor

We stayed for two nights Oct 5th & 6th. Check in & check out process was easy. Bed was comfortable. View of Detroit across the river was nice. Bathroom was nice with plenty of counter area and walk in shower was nice, especially for people who find it difficult to step into a tub/shower. Fridge was good for chilling wine. Fitness room was good with plenty of equipment and secured lockers. I thought the hotel could've offered complimentary coffee in the lobby. Instead, guests are required to purchase Starbucks coffee in the small market for purchase area near the lobby. Also, we found the tv channels were limited, specifically sports channels. On the second evening, our air conditioner/heating unit on the exterior wall started making noise. The noise got loud and continue but eventually would decrease then quiet for a while then increase and get loud again. We called the front desk and eventually a maintenance staff came. He looked at it and eventually determined that in order to find the source of the noise, the wall unit would have to be taken apart and would require two staff and take time. So, he apologized and gave us a blanket to cover the unit to muffle the sound. Although the bed was comfortable, the noise didn't make for a great sleep. Upon checking out, which was easy, we took our luggage to the parkade where our vehicle was parked. We paid $34 for both nights. The parking ticket that I was issued upon check in remained in my wallet for the two days since we never did drive during our two night stay. Upon exiting the parkade, I put the parking ticket that I used to enter the parkade into the ticket dispenser where it indicated that I owed $32. Knowing that I had paid $34 for two nights of parking through the hotel, I was a bit confused. I backed up and parked the vehicle and called the front desk. The front desk agent told me that I had to call the parkade assistance to discuss this problem. So I went back to the ticket dispenser, selected the assistance button, spoke into the dispenser and explained my situation. The operator instructed me to cancel my ticket submission and retrieve my hotel parking ticket. However, my ticket didn't return to me. Likely because others may have exited the parkade since my attempt. The parkade operator instructed me to go back to the hotel and get this problem corrected. So, I walked around the block to the front of the hotel, since I no longer had access to the rear of the hotel, and again told the front desk agent my situation. I was subsequently issued a new ticket which I then used to exit the parkade. What I didn't appreciated from the hotel front desk was being placed in the middle of a problem between the hotel and the private parking company. This wasn't my problem but the hotel made it my problem to solve. Overall, this isn't a bad hotel but two significant incidents made our stay less than memorable.
