This unit is essentially a one bedroom condominium with a fully equipped kitchen, living area, and dining area. The bedroom has a king size bed, and the bathroom is equipped as one would expect. The square footage for the price considering this location right in Vail made this an excellent value. The two things that disappoint me regarding the property are the fact that it is feeling a little tired and smells a bit moldy inside and also the exterior window, for the living room is tucked back in a dark corridor, so there is very little of any natural light that enters. The bed was comfortable, the kitchen was fully equipped, and everything worked perfectly. When I first arrived, there was not an available parking spot due to sloppy parking by other guests. Spots did open up though and I was able to park in the lot for the nights that I was there.
