As a solo traveller, I stayed here for one night on the way from San Sebastian to Madrid.Burgos is a wonderful small city that I most enjoyed.
Having booked through Tripadvisor, I had gotten a good rate that did not include breakfast. Reception staff facilitated an early check in for me circa 12pm and were helpful, but not particularly warm or welcoming.
The location is super - right across the river from the Cathedral and many other attractions.
The room was just fine and very comfortable. I did not have breakfast in the hotel, instead visiting a nearby cafe. I did have a drink in the bar on the night and the barman was excellent - engaging, chatting to customers and providing excellent service.
The building itself was originally an old monastery or some such and the restoration work has been brilliantly done.
I would recommend this hotel.
