We were there for 5 days. It was impeccable. The location, service, ambiance everything was perfect! All small attentions that makes you feel comfortable. We took the water taxi from (and to) the airport directly to the hotel fastest way to get there. Easy to walk around and along the waterfront. Breakfast was excellent

Was looking for pet friendly on the beach for a long weekend on the Cape. I hadn’t been to SeaCrest in over a decade. Property was in great shape and looked like it was recently renovated. Fireplace studio was great with a view of Old Silver Beach. Beach service was quick and efficient. There were several events on the property and noise was never an issue. Meals were great. I wish the pizza place was open!
