These distances are exact, but are based on a straight line from point to point. Actual walking distances will be slightly longer.
Nice room and quiet location, but problems with the toilets and showers - no hot water and two toilets with broken flushes, you had to fill the cistern yourself with a bucket. The only working toilet on the other side of the convent. The whole building was a bit rundown.
Also check out zaguán de la plata ( shown on the map ). We paid 12€ each for my wife and I and had our own room. The hostel served a really good breakfast and a beautiful garden with swimming pool, hammocks, bbq, and fountain
