We were 3 couples at Luca’s place, but unfortunately the house is not suitable for 6 people, at least during the hot summer months. The small room was extremely small and most important, extremely hot. There was no air conditioner, rather a ventilator, which was completely useless during the hot summer months. The host offered a second ventilator, but it did not change much. This ruined the stay for 2 of us, and we used also the small sofa in the living room for sleeping. I should mention that an air conditioner there would have greatly improved the overall experience.
Other than that, the location is perfect, and the the rest of the rooms were ok. The bathrooms were rather small, but on the plus side, each of the couples had his own bathroom. Another minor problem was that the biggest room above the living room, which was reachable by the stairs, did not have a door. This affected the privacy as you could hear everything in the living room and vice-versa.
The house was generally clean, but one of the bathrooms had a really dirty trash, which was smelling bad.
