This was my third time staying at Villa Sumaya. The big change is that the owners are no longer on site and they have left the hotel to be run by a manager. The manager is quite good, but it isn't the same as a family-owned hotel. Additionally, they did away with the video room that was there when I last visited. So the nights are very quiet -- it would have been nice to have that amenity so that my girlfriend and I could watch videos after dinner because there is nothing around to do whatsoever.
NEVERTHELESS, Villa Sumaya is the perfect respite. I love the rooms, the food is good (Domingo is a fantastic cook who will prepare whatever you'd like), the location is superb, they have thought of every possible point from which one would want to relax. Nothing short of fantastic.
You may also wish to examine Lomas de Tzununa, which I found while hiking from village to village (there is a great path not to be missed heading towards Santiago). They have better food, splendid views, are more isolated, and run by a wonderful Uruguayan-Belgian family.
**Be forewarned that when you catch a lancha (motorboat) from Panajachel, the boys who collect the fares are ready to rip you off. It should cost only Q10/Q15, and they will ask for Q70. Hold your ground, tell them you have been there before and know it is only Q15. **
