This gem has been carefully crafted by its owners Wendy and David to cater for discerning travellers, seeking stylish accommodation, excellent food, and outstanding views in close proximity to the sea. Simply outstanding.
A nice quiet hotel with fantastic views.
We were upgraded which was a bonus, the room was spacious and tastefully decorated.
The staff were great and so was the food.
Stunning location, Stayed in Steffi room - Very Comfortable Bed with tasteful decor, modern spacious bathroom with fab walk in shower. Would have liked a magnifying mirror for make up / shaving. Evening Meal and breakfast high standard great produce all cooked to perfection.
Staff very friendly and welcoming. A wonderful relaxing break. Highly recommend.
Stunning location & beautiful property with lovely views.
Ideal for our anniversary stay. However, not suitable for those with a fragrance allergy unless you take your own towels, loo roll and sanitiser. The towels are laundered on-site and are fragranced. Also the loo roll and sanitiser is scented.
I did request (in advance) no fragranced products as I have an allergy to them but this was not provided. The bathroom was unbearable.
The staff did try their best and provided a towel washed without fragrance but I did not receive it until 9.30am the morning we were leaving.
The food was very good and locally sourced.
A lovely boutique hotel with beautiful views over the bay
Spot on service with a special mention to Hannah Great chef and dinner beat expectations
Large well equipped bedrooms

Beautiful contemporary bedrooms, location stunning, unfortunately the restaurant ambiance , food quality and service somewhat disappointing, the room is more like a large function room so do not expect an intimate restaurant, feel that they could improve as the entrance, bar and rooms are lovely
Very friendly and helpful staff. The location is lovely: very quiet and a wonderful view! Room was very spacious, luxurious finish, amazing bathroom. A must stay when visiting this region!
Why travel abroad, when this gem of a place is so close to home? Just returned from Mansion House, Llansteffan feeling totally relaxed and refreshed. The views were fantastic, the staff extremely friendly and nothing was too much trouble. Our room and the restaurant were spotlessly clean and the ambiance was perfect. We will certainly be returning.
Diolch yn fawr am wyliau byr perffaith.
The food was not as good as it advertised, the cups have stain mark in it, didn't use it.The bathroom is not as clean as it shown in the picture.Also the service not very good, we went in the room there were only 7-8piece facial tissues left in the box, when finished asked for another one, but the staff said there should be enough, and never brought to us later.
