This is a great place to rent, size, comfort, and location! The beds are comfortable, the AC is excellent to have, and the washer/dryer. The management company communicated often, but there were multiple emails from several people, so it could have been clearer who to speak to directly. Horizon helped us with the check-in (the unit was not ready at 6 pm) but offered an incredible recommendation to a local restaurant (Mariajuana with Oscar and his family). It was the best meal I had in Tamarindo!
For the unit, the size is lovely for two moms and two boys and could easily fit more with a sleeper sofa. The furniture was comfortable, pots, pans, etc. We felt safe, with a gated area, cars locked behind, and easy check-in with key code and leaving gate key on the counter when departing and exiting through the gate. The water pressure is low (not sure if this can be fixed), and the pool area is not the cleanest (the hot tub did not work at the time with jets), but it is a nice amenity.
