Everything was great. The hotel is in good condition, the rooms (including beds) were comfortable and the bathrooms simple but nice. The staff provide a simple but good breakfast (Western-style) to get your day started. The location is on the key side-street that leads to the beach, and is among restaurants, tour agencies, shops, and some bars (present but not bothersome). It is just a minute's walk to the main road, and you can get a massage within a few steps! They have a comfortable lobby and porch for a respite any time of the day. And the view from rooms facing the back is a pleasant grassy area beside a pond, with trees.
Above all, the staff were great! Co-owner Visa was immensely helpful in salvaging a plan for our last day, which we had neglected to plan ahead. It turned out to be the best day of all!
I highly recommend Nautical Home & Seashell House for a pleasant stay in Khao Lak.
