For a hotel that feels like a (n American style) hotel, try the Hotel Presidente. Free hot breakfast, security, digital keypad lockboxes, spa, casino on premises, WIFI, no fee for one girl visitor (dress code strictly enforced)...and if you pony up the $39.00 to join CRT V.I.P., a nice discount on your room.
I wouldn't really call the Sportsmen's a "hole in the wall," it's quite nice, modern amenities...but sadly, it is probably booked. Contact them at
info@sportsmenscr.com and ask about a room in the new wing. You might get lucky...a 25 room boutique hotel with a Cheers-like bar environment, great food, satellite sports and yes, hookers (independents) who work the bar.
May I kindly suggest that you visit the Newbies' Section and read a couple of the sticky topics, including Ace's terrific lists. Visit the "Massage Parlor...." section and check out RBC100's "Massage Parlor and Tico Bar List," which shows locations, hours and prices.
Welcome to CRT, and buen viaje!

Also, if you join V.I.P. you will have access to a beautifully done, printable map showing all the places you might want to visit on your trip.
