Tomas's carriage house is just as great as everyone else says it is! I stayed for 4 nights during a work trip and it was perfect.
The location is great (the Denver Botanical Garden) is right around the corner. Street parking was readily available. The house itself is cozy and Thomas has been thoughtful enough to provide you with standard kitchen staples (a Ziploc bag came in handy!) in addition to the stocked bathroom and medicine cabinet. I ended up being too tired to cook, but the kitchen has everything you'd need and there's plenty of room to whip something up.
I would definitely recommend stay here and look forward to returning when I'm back in town.
