We were a group of 9 people and a dog that went to stay in Sebastian's house. The distribution of beds worked out perfectly for us, since we were 2 families with kids. There were lots of common areas to relax and play games. The kitchen was spacious and well equipped. The surroundings were so peaceful and beautiful. It was so great to wake up and jump into the pool instead of having a morning coffee!
The house is in its own little compound, in Llucmaçanes, which is a beautiful area nestled between Mahon and the airport. I was worried that the sound of the planes would bother us, but hardly noticed them at all. Getting in and out of Llucmaçanes is a bit trying, the roads are flanked by stone walls, which looks very charming but gut-wrenching if driving a large vehicle (I was driving a 9-seater van!).
I highly recommend Sebastian as a host and his home as a place to stay when in Menorca.
