This is an incredibly unique place to stay! There is a ton of beautiful outdoor space, and there are plenty of bathrooms if you are with a big party. The service was wonderful as well - each morning, the attendant made coffee.
I would say the ideal amount of people to stay here is 8-10 but I was with a bachelor party of 13 people for 3 nights and we loved it; we just had to double up in several of the beds.
Highly recommend staying here, and Lorenza, the host, is a sweetheart!
