We had a great week in Tamarindo.
The condo was exactly as shown on the picture and as described. The property (Los Suenos II) is also very nice, quiet and well maintained. It actually looks even better than the pictures!
It is a 5-minutes walk to the closest restaurants/bars, 10-minutes to the main street and the closest grocery store and 15-minutes to the beach.
We travelled with our 3 and 5 year old and brought a large double stroller which was the best way to travel from the condo to the beach and carry all of our stuff on the rocky, uneven roads.
The onsite management team was not the best we have seen. We received arrival information from the property manager, Rosa, but she was not there when we arrived. It took us a few minutes to figure out who was the security guard on site who was supposed to have the keys. She never tried to make contact with us while we were there. Her husband, the groundskeeper, tried to have an air conditioning unit installed at the house on our second-last day while the kids were napping.
The condo has a well-equipped kitchen (no microwave or oven, but we did not need those). There was none of the basics (salt, sugar, dish soap, laudry soap, garbage bags, etc), so make sure you bring them or buy them when you get there.
They had towels (5) for showers, but you need to bring your own beach towels.
Tamarindo has a very nice beach. Perfect for kids. It also has lots and lots of delicious restaurants. All the ones we tried were great!
