We did not book in advance, just went there and as we checked some places to sleep before we arrived and went to Cabinas Marcelina.
We booked a 2 bed room and added an 3rd bed inside as it was cheaper than the triple room (online the triple room was 55$).
There is hot water, wifi & aircon available. I would say it is a good place to stay for the night.
FOOD & DRINKS
Restaurants, we checked Trip Adviser. Had dinner at Marisqueria Corcovado which is just next to the port. For the place I guess it was good,fish was fresh and service ok; if I compare it with other fish restaurants around Costa Rica I would say this one is average.
We did not have lunch instead we got inside a bar had some Imperial beer (as I preferred it to the Pilzen) and we could 'order' some chicken wings from across the street. Watching Champions League and later one some Latino music on the background.
