We really enjoy our stay, we were a group of 10-12 young friends and had an overall good experience; I've listed some pro/cons on this property so that you can have a better picture on what to expect.
The house is really nice, with nice decoration and in a really quiet enviroment. Is great for a weekend with friends and/or family.
Beautiful garden, with a small pool and, since this is a beachfront parcel, you have an outstanding ocean view from the terrace.
The beach is quiet and really nice too, we have been alone the whole weekend and could enjoy a lot there despite the weather was not the best. Please don't expect a caribbean beach! this is a regular Panama pacific beach, similar to Buenaventura, warm temperature, it is not fully transparent and have some few waves.
There is a big supermarket 3 min from the house, that's great because you don't need to bring everything for all the days that you are staying.
The BEST 2 things are: 1) The HUGE open terrace with ocean views, oustanding for a get togheter, eating, bbq, etc and is also very well mantained, 2) The Staff (Mery & Francisco) they were really kind to us, helped a lot cleaning and mantaining the house in order and in addition very polite and on top of everything we need.
The "not so good" things you should consider are the following:
1) Actual Capacity: Although in the publication says "Sleep 12" the house has real space to accomodate 8-10 people in 3 bedrooms with a total of 4 queen/king size beds. The 4 extra places to reach the 12 are cots that can be placed in different places of the house or directly in the bedrooms. Bear this in mind because the price is considerably higher for each new guest (aprox $100 per guest per night). In addition there is a fridge in the kitchen that is kind of small to keep food for 12 people staying 2-3 days, and there are not enough plates/clutery for 12 either, so consider this when planning the menu. There is a big freezer so maybe is better to keep your things there frozen or buy in the supermarket what you need for each day.
2) Mosquitos/Bugs: Be prepared! in the afternoon/evening you will be welcomed by a cloud of hungry mosquitos/chitras, I think that this may be worse during the panamenian humid season (form Apr to Dec). We stayed in Nov and we literally had to cover ourselves in strong bug repellent! There is no closed living room or get-togheter space so unless you go directly to the bedroom there is no escape from them!
