We had an amazing stay at Mark's lovely condo in the Los Suenos resort. Keylor and Larry w/Costa Rica Dreammakers (property management company) were super helpful before & during the stay, especially w/booking a fishing charter (best way to ensure you aren't taken advantage of by the "deals" down at the beach area), renting a golf cart and car, & airport transportation to & from the condo.
The photos on the listing really don't do it justice. Everything was clean & comfortable, with plenty of towels and almost everything in way of kitchen-ware (the only thing we didn't see/find was a baking sheet). The balcony views in the AM (macaws & many other native birds) & sunset views in the evening were breathtaking. (Hint - you can get the best sunset pics from the grassy area between the closest pool & golf course - also fun to watch the egrets fly in & hang out in a tree as the sky turns pink, red, or orange, depending on the day.)
I definitely recommend this resort for a first trip to CR. The Beach Club is beautiful w/good food - but beware of the drink prices, which are not advertised (they charged me for each part of a paloma bringing a 12 ounce drink to almost $20). Jaco isn't too far (you will need a car) & the mid-week Farmer's Market is a must for the best produce, eggs, & meats. The grocery stores in Jaco have better prices also - though next trip we will rent the car in San Jose & shop there before heading to the beach.
All in all, great stay and hope to return soon!
