We stayed overnight in Hotel Marfrei having driven across Spain from Murcia before getting the ferry from Santander the following day. The location of the hotel and the building itself is pretty, quiet and picturesque, we had a lovely view over the Cantabrian countryside from our room. The room itself was spacious with a good-sized ensuite bathroom, the bed was comfortable and the room was clean and nicely decorated. The staff were also very friendly and accomodating. My only slight negative was the quality of the breakfast, there was quite a small range of items in the buffet but I suspect a lot of this was down to the time of year and not many guests in the hotel (we stayed one night mid week). However, they did cook you fresh bacon and eggs if you wanted it - otherwise a couple of cereals, rolls and cakes, some ham and cheese, and bread for toasting. Overall, we paid around 60 Euros for both of us for a one night stay, the hotel is good enough as a base for longer stays and for the price we paid, the slightly lacking breakfast wasn't a big issue.
