Luisa's house (or better maybe called estate) is just amazing. We were there with two research labs, 13 people in total. We had an amazing time, the house is just perfect for large groups. It has everything you want to have, great rooms, living rooms with fire place, many bathrooms, great kitchen, pool, BBQ, washer & dryer, parking, great outdoor areas. We basically stayed there the entire time, cooked ourselves, discussed science in the large living room, and went hiking in the beautiful surroundings. I really want to come back for holidays, it is really a perfect spot for 10-20 people. The host was very responsive and everything worked like a charm.
