I stayed in the Sercotel for a week when I arrived in Soria to teach English. Overall, my stay was pleasant and comfortable. The rooms were cleaned daily, sheets and towels changed regularly, and plenty toiletries provided. The room was basic, but had everything that you needed. The breakfast was included which was nice, although there wasn't a huge selection - some fresh fruit would make a nice addition. The hotel is located a short distance from the centre of the city, the bullring and the bus station, which was ideal for my needs. All in all a very good stay.
