This comfy B&B in residential Escazú is a quiet, homey escape run by Tiger, an attentive former nutritionist and personal trainer who makes art and cooks brilliantly (meals US$10). Guests here are frequently medical and dental tourists, and Tiger can cater to their diets. Prices drop for longer stays, and the host prefers a minimum three-night commitment.
Ask Tiger for directions, or consult the rather specific ones on her website.
