I didn't actually stay at this place, but checked it out, comparing it to the place I stayed next door (Las Brisas).
The common areas at the Alamar were quite well tended, and the pool area was lovely. the restaurant was very attractive though I haven't a clue what the food was like. The reception staff were very courteous and one of them showed me to a room to consider it for a return visit to Puntarenas. Modest and clean. It had a coffee pot, glasses, air conditioning, a chair. The bedspreads and curtains looked old and tired. Bummer.
I guess I would try this place because appearances matter to me, and considering what we had to contend with at the hotel next door, looks like the best bet.
And it was considerably cheaper, which is a consolation.
Good luck to any of us if we must stay in Puntarenas!
