Lovely B&B.....very friendly host and staff.

Nice clean large room. The fridge was a big bonus. Excellent shower which was much appreciated after a long day walking. We were led to believe from the hotel.com web site that there is Wifi only in public areas but in fact there was wifi all over the the guest house including the rooms. And it was super fast wifi. I was able watched Netflix on my ipad and all the football matches I wanted to watch. Moyra (the owner), is a lovely friendly lady, as her staff. Breakfast was fabulous, continental and cooked what ever you choose or both. We will definitely come back as we have few more walks to complete in the area. Thank you Moyra for a lovley weekend.

Lovely accommodation, with friendly staff who were very polite and helpful. The room was very tidy and clean, the only con would be the mattress was slightly uncomfortable with old springs. We overlooked that as the property was perfect for us.

Lack of hot water

Day before had phone call from owner informing me that the room we were allocated has a toilet problem and we might have to be re allocated a downstairs room if the problem not sorted, luckily it was. Shower and sink in room kept loosing water and were not warm. Mentioned to owner the following morning and was told they would be sorted. Arrived back after day out to a written note on how to keep water running and warm, but it still wasn’t warm and was water was stopping mid use. Mentioned again at breakfast to owner for any other guests. Owner mentioned that staff levels were down. Breakfast was really nice and fulfilling, staff were very friendly and chatty.
