Absolutely superb. Potes is a great launch pad to or rest stop from walking in the Picos Mountains. The apartments are well located centrally in Potes - slightly away from the main drag of bars, restaurants & noise. Well equipped, clean & a friendly owner who also runs a local hostal and the Plaza Restaurant (he will give you a 10% discount on meals). Easy to drive to or catch the bus from Santander. Wonderful place & would also recommend El Rebecco at Fuente De.
