For a month long stay in this price range Mariber is, by far, the best we have stayed in. It is spacious, exceptionally well screened, clean, has an unusually well equipped kitchen, is comfortable and is in a convenient location. We like to walk so we walked to "town", to Flamenco, to Tamarindo. Alternatively, one could catch a publico to Flamenco by standing outside the airport gate, just across the street. As the airport IS just across the street, expect to hear every arrival and departure as well as the sounds of traffic. However, by early evening it is usually quiet (with the exception of Christmas week and the week leading up to it). One of the pleasant sounds at that time of year is of the horses passing as Three Kings Day approaches.
To go further afield, e.g., Zoni Beach and to explore the island, a vehicle or golf cart is needed.
We found the ceiling fans adequate for comfort; we did not need to use the air conditioners which are in both bedrooms and the kitchen. We enjoyed eating our meals on the screened in verandah but could have chosen to eat inside. The lighting on the verandah, and in the living room, was comfortable to read by at night, another "plus" for Mariber. We appreciated the use of the very good washer and dryer under the agreed upon terms.
The owner was most accommodating and very pleasant to deal with. We certainly recommend Mariber with the proviso that you will be aware of numerous flights (small planes.)
