We stayed here as we were sailing from the port the following day. It was a great find, with cheap parking, friendly staff with great English, a decent breakfast and a perfect location to explore Santander. We decided to go out on the evening we stayed to have dinner. The city is a half hour walk or a very quick and cheap taxi away.
The staff allowed us to leave our baggage behind so we could explore more the following day, before our boat. Would happily stay again.
