Check in was simple. Patrick was very friendly and helpful. We wanted to extend our stay, and that wasn't a problem, and then it was easier for us to checkout later because of our toddler napping, and that wasn't a problem either.
The flat was very nice. 3 bedrooms on top, wood floors throughout. 2 and a half baths. Nice kitchen, dining room/living room. TVs in 3 rooms, though we only used one. It has a nice little graveled courtyard that our toddler enjoyed as a play area.
The location was great for us, maybe 10 minutes from the strip, close to the Boulder Station. You'd definitely want a car. It has a two car garage with automatic opener. Also a washer and dryer in the garage.
He left bottled water for us, and said we were welcome to the beverages in the fridge. Very generous. Highly recommended.
