We had a wonderful stay at the apartment in Sobranigues, which is a cloister of beautifully preserved medieval buildings. The apartment is small (as described) but accommodated our family of four and was perfect for exploring the surrounding area including Girona, Fiqueres, Tossa de Mar, L'Empuries.
Sobraniques does not have any amenities, you will need to drive to surrounding towns for grocery or cafe. The flipside of this is that the area is very peaceful -- stars at night, birds in the morning -- and there is a wonderful walking/jogging/biking path minutes from the apartment. The space itself is in an ancient structure outfitted with a modern design and amenities (wifi, heat pumps). There is a bit of magic to staying somewhere so old and getting the smallest glimpse into what life might have been like 500 years ago, just by staying within those old stone walls and walking along the cobblestone paths.
Beto, thank you for sharing this special corner of the world with us!
