Pere Miquel is a perfect host - nice and very helpful!
The house is just a dream, very well equipped - I cannot even think of something that is missing (of course the absence of WIFI is a feature).
Everything is nice an clean - and exactly as shown on the pictures.
There is also a wild garden (containing little turtles, my children loved them), there are canoes (it is only a few minutes down to the beach), you can play table tennis or jump in the pool. Perfect if you want to relax.
There is one thing you won't find in Betlem: hurly burly animation and action, places crowded by tourists or a ton of infrastructure. One nice restaurant and that was it - a car is definitely recommended. Hordes of tourists and the usual booths, restaurants and offers are about 10km away, in case you need that.
TL;DR: The perfect place for a relaxing peaceful holiday at a reasonable price.
