Finca Montuiri is a wonderful house located in the midst of olive groves. It's a comfortable place for 18 adults and 2 kids! Every room counts with its own bathroom which makes things much... easier and faster. House is perfectly equipped with kitchen tools, stereo, outside and inside furniture, umbrellas, etc. So you can kick back and enjoy your gatherings. Patrik who let us in was extremely friendly and easy going, we were even allow to stay bit longer as there was no one coming after us. It's note worthy to add that the village is visible from the house (close) but you are in the middle of nowhere, so loud music, singing and any other noise will not bother the neighbors.
I very much recommend renting the house!
