We stayed for just one night at Leland House B&B but would love to come back. I describe it as a quaint place and friendly experience. Downtown Durango is not that large, but this is at the heart with all the shops and restaurants nearby and in the morning we walked to the train station, maybe 5 minutes by foot.
When we arrived, the staff had already opened our room, the lights were on and music playing softly, very welcoming. As others mention, the included breakfast was very nice - quality ingredients. You'll want to ensure at least 30 minutes because the special dish is made fresh once you're seated. Besides the special dish, there was coffee, juice, milk, cereal, yogurt, granola, hard boiled eggs, and pastries.
The bathroom was on the small side (not a complaint, it's an historic building), but very nice, as was the bed and bedding.
My only disappointment came at check-out time. The person who mans the registration desk had left to tend to some breakfast diners outside. After asking nearby staff twice when she might return, someone jumped in to help me check out. Nothing major, I've just grown accustomed to turning in a key and leaving and it took maybe 5-10 minutes to do so this visit.
Overall a wonderful place and very nice staff, would recommend a stay here when you are in Durango.
