Niwot Inn & Spa

Longmont

10/10 Excellent

We came to Longmont from Portland, Oregon, for a class and chose the Niwot Inn from the options we found online. I thought it was going to be a place to stay and instead it was an experience to remember. It is warm, welcoming, and relaxing, gorgeous to look at, and did I say relaxing? Sitting in a comfy chair in the evening in front of a wood fire and eating a warm cookie had me relaxing like I haven't in a long time. We met the owners, a mother-daughter duo who are proud of their lovely inn and...

10/10 Excellent

This is our 2nd stay and both rooms were great. Stanley Steamer and Dunraven. Overall fantastic location and lodge. Service and staff were great. The beds are very comfortable and great balconys. I do have a few suggestions. Add a small refrigerator in the room and a small common area microwave/ coffee station. Logistically this may not work but it would be a huge convenience.. Thanks again for the great weekend stay and we wjll be back again soon.

Cliff House Lodge B&B

Morrison

10/10 Excellent

My partner and I fell in love with this hidden gem, and frequently return for getaways from summit county. Whether we are going to a red rocks show, or running errands in Denver- once we discovered Cliff House, we have never stayed anywhere else! However. We've always paid about $200 a night which is a fair price for the cottages we've chosen... I tried to book a night in April, and it is over $400! That is really disappointing as that price is not reasonable, and I will not be able to return...

The Estes Park Resort

Grand Estates

10/10 Excellent

Beautiful hotel right on Estes Lake. The rooms were cozy with our own fireplace and the balcony lake view is worth the upgrade. The drinks, dinner and service at the Ember restaurant was amazing and everyone at the front desk was so welcome and friendly. We also enjoyed the little game room with all the different board games. We were bummed to learn there is no pool on site and told by the staff that Expedia needs to update their property details.
