Hotel Santemar

10/10 Excellent

"La cercanía con lugares turísticos es muy buena, la atención del personal fue orientada a un buen trato, habitaciones cómodas y limpias."

Hotel Bemón Playa

10/10 Excellent

"Tucked out of the way, Hotel Playa Bemón became a refuge for me from the hurly burly of both Santander City and the more conspicuous hotels in Somo. I enjoyed a magnificent two nights of perfect sleep. There was also the business of a delightful 30 minute ferry ride from a cute little slip just a few minutes walk from the Santander bus depot. All of this just totally enchanting. In the evening glorious sunsets from the beach at Somo, overlooking the bay and Santander. The Hotel staff was friendly, helpful and efficient. No complaints of any kind, really. On both mornings of my two-day stay I ambled over to the Somo beach and found surfers galore--there was an international surf meet going on--and delighted in watching them ply their skills on the waves. "catch a wave and you're sitting on top of the world" the Beach Boys sang back in the early 1960's. True to form here. I also enjoyed a fantastic dinner in one of the sophisticated eateries in the small town of Somo. Fresh seafood, good wine, excellent service. I highly recommend the experience of visiting Somo and staying at the Hotel Playa Bemón."

Castilla Termal Balneario de Solares

10/10 Excellent

"best breakfast ever, great mattres and clean place, near every thing!!"

Dorma Sardinero

8/10 Good

"Great breakfast! Had a room with fabulous view. Bed was comfortable. Lucked out with nearby parking. Biggest discouragement was the black mold around the window and black mold on ceiling in bathroom. So simple to clean."

Hotel Picos de Europa

10/10 Excellent

"We arrived at 1pm and were able to check into our room. Very clean, powerful shower and small bottles of complimentary water and toiletries replenished each day. Great location for walking around the city. Hotel guests receive 10% discount off menu del dia, served 1pm-4pm - choice of 3 starters, mains and desserts and includes bread and half a bottle of wine each for €18. The Rioja wine is very full bodied. Highly recommended for authentic home cooked Spanish food. Would highly recommend this hotel."

Hotel Citrea Santander

10/10 Excellent

"Todo muy bueno"
