We stayed at Alberto's place for 4 nights and the overall was nice.
We had only 2 problems. 1st was a fridge that we had problems with.
2nd was cold floor, so you better take warm socks with you!
Alberto was very helpful and gave good directions, but make sure you will arrive during day time, trust me you need all the light you can get to get there!
All and all, it was absolutely wonderful trip!
