This condo is clean and has a kitchen with all the utensils you need. It’s close by the village where restaurants and shops are located but it’s a work out walking up the hill. They offer bus transportation but we didn’t get a chance to use since we only stayed for 2 days. Parking is included which is great.

5 stars for a great location, extremely clean facility, friendly staff, spacious 1 bedroom unit, bar & grill on site and complimentary hot/cold breakfast & hot chocolate and cookies after skiing. Located on the east end of Vail, it's perfectly situated if you want to be walking distance to the Village and the Ski School. Free bus shuttle into the village & lionshead if you don't want to walk and very simple to navigate. Lionshead is approx 1.5 miles. Complimentary ski valet at the base of Golden Peak. A great location for easily accessing the back bowls at the Vail ski resort. We stayed in LionsHead last trip and it took some effort to get in the back area of the mountain. The complimentary breakfast buffet from 7-9am was fantastic-included an omelet station along with 4-5 buffet trays that had take out options if you didn't want to dine in. 4 stars for my 1 bedroom condo (081) which was in the basement facing the back creek in a building where the only elevator getting downstairs was broken. (not a platinum or diamond level if you care). Location within complex made up for it as it was steps from the Riva Bahn lift and close to pool/hot tub. Comfy bed, great shower but bathroom tight considering the size of the unit. Even though its a condo, there are hotel like qualities - daily garbage removal-fresh towels-bed making. Service was great and the cleaning crew was nice! Manor Lodge pays attention to the small details, we would stay again for sure!

Hotel is nice enough and comfortable. Kinda silly they charge you for parking a car there...seems like for what you're paying a parking spot should just be included. Wish breakfast started earlier than 7 am - If you're working in Aspen and need to get ahead of traffic this is pretty late.
