Velingrad Hotels with Tennis Courts

"This hotel has a nice small outdoor pool open through the winter (08 am through 20-00) where thermal water stays sufficiently warm, and a warmer indoor pool. Sodium-fluoride waters are nice. The breakfast buffet is good and accommodations are comfortable (although unfortunately no kettle in the rooms). Good wifi. Straightforward parking and late arrival is possible. If you start hiking up the hill from the hotel you can join bicycle trail 220 going up to Ostrets peak (elevation gain of around 800m round trip counting ups and downs). "
