Mark was a wonderful, responsive host who answered our questions (and there were only a couple) very quickly. The house was terrific for our multi-generation family of 10 (grandparents, parents, and young adults). The location was great - a 20 minute walk on sidewalks to downtown Sag Harbor. The pool, large dining room and kitchen, and spacious, comfortable bedrooms all made our vacation just perfect. We highly recommend this house!
