The trullo was fun to experience, and it was cosy and pretty inside. It's definitely on the small side for four people, particularly in winter when we were inside a lot. It was an extremely cold week and the pellet heater struggled to keep up. We had expected the surroundings to be more rural and idyllic, but there's quite a bit of suburban untidiness around the trullo (although the centre of Castelvecchio is pretty, the outskirts including the walk into town are not especially lovely).
