My husband and I have visited various parts of Costa Rica for the past five years (West side, Caribbean side, Manual Antonio/Quepos, Atenas, Arenal, Monteverde....and places in between). For the past two years, we have been fortunate enough to stay at Casa Celeste (both times, for about 8 days each). It is hard to capture the perfection of this property. In short, we'll never stay anywhere else.
First, its location: It is on the beach (few houses in this area are) in a quiet and serene part of Mal Pais. I feel as if I'm in a nature reserve just sitting in the yard!! (Speaking of nature, you can see iguanas, monkeys, wild horses, birds -- all kinds of things!) The views are breathtaking, and the tide pools out front are always a blast to explore. It is very close to Santa Teresa (where the stores, restaurants, surf shops can be found), but is far enough away from all of that for those who appreciate a nice respite and who are seeking some peace, serenity and nature.
Secondly, the house itself. It is adorable, with a great covered patio (great for watching the rains come in the afternoons, or for escaping the sun when needed!). The view from the kitchen is amazing for those who wish to cook. (We cooked in most days....its hard to leave the property its so nice!!) The beds are incredibly comfortable, and there is AC. For those new to Costa Rica, trust me, these are amenities that are NOT typical.
Finally (and most importantly), the caretaker Vicente is the most amazing man I have yet to meet. (Not to worry, my husband knows I feel this way -- and he agrees!!) While he is there to ensure your satisfaction and your safety, you will get SO much more out of meeting him. He is wise, kind, loving, and generous. We feel we leave there better people as a result of spending time with him. He quickly became (and remains) one of our dearest friends. He will be there to answer your questions as much or as little as you'd like -- so you definitely still have privacy, but you have a "go-to" guy if you need it.
Oh! And I'd be remiss without mentioning how wonderful Diana and Ran are to work with. They are quick to respond and incredibly professional. Between them and Vicente -- you will be well taken care of!!
