We stayed at Mikael's place (both floors) with a group of 8. The house is beautiful; very clean and fantastic views over the coffee fields and ocean. We thoroughly enjoyed our stay, and especially enjoyed the fact that we could use the beach chairs/coolers, etc. from the house to take to the beach.
The design of having to walk through the bathroom to the bedroom we didn't find great - the sliding bathroom doors facing the common area don't have a lock, so take that into account if you need this level of privacy. Finally, there are quite a number of post-it notes all over the house with rules, this sometimes felt a bit intrusive. I understand it is hard to keep a house like this in perfect state, but maybe it's a better idea to add it all to the rental contract instead?
Either way, we had a great time here and would definitely return.
