We decided to stay at The Residence Inn during our one night in Boulder and were disappointed in this choice. While it garners above average ratings on this site, among others, I would describe the model and the specifics of what is offered as underwhelming and outdated. The rooms lack a freshness and are designed to emphasize the requirements of a long term occupant - the kitchen for example dominates the space while the balance of the quarters feel stingy and plain like a motel room that missed the last renovation cycle.
It's location is off the beaten track if that matters. The staff is pleasant and very helpful despite having little to work with.
All in all, an overvalued evening for what the Marriott is offering.
