Lanelay Hall Hotel & Spa

10/10 Excellent

"We stayed overnight at The Langley for a spa day and it was a beautiful experience from beginning to end. The hotel is stunning — elegant, well kept, and with a real sense of occasion the moment you arrive. We were kindly upgraded to a Courtyard Room, which was gorgeous and added something special to the stay. The whole setting is relaxing and indulgent, and the staff throughout were warm and attentive, making us feel genuinely looked after. Paired with the Tribe Spa (where we had fantastic massages), it made for the perfect getaway. We couldn't fault a thing and would happily return. Highly recommend The Langley for anyone wanting a touch of luxury and a proper escape."

Blanco's Hotel Port Talbot

10/10 Excellent

"Ideally situated for visiting Port Talbot and the Gower peninsular area. The hotel was very clean, all staff very friendly and helpful (no problem each morning getting my gluten free toast) and even the basic room is lovely and spacious. Loads of parking right outside. Breakfast buffet has a good selection of foods from fruit/cereals/cooked options and sweet pastries. The only slightly annoying thing though, is it's just off the M4/A48 junctions, so does mean if a light sleeper it can be a bit noisy with road noise, even overnight. Maybe would be quieter if you ask for a room at the front of the hotel?"

Delta Hotels by Marriott Swansea

8/10 Good

"Good location and a comfortable stay overall. The hotel is a little tired in places and there were lots of dogs around, but the bed was really comfy and we slept well. Breakfast was excellent with a great choice and was definitely one of the highlights of our stay. Lady hosting breakfast was lovely, a highlight of the holiday being greeted by a lovely person."

Holiday Inn Express Swansea - East by IHG

Village Hotel Swansea

8/10 Good

"Clean and very spacious room, reception rep was extremely helpful with a booking issue."

Nant Ddu Lodge Hotel & Spa by Belvilla

8/10 Good

"Room seriously needed an update. Hand held shower in the tub is poor in this day and age. Food was good - had dinner both days and was well presented and tasty. Staff were very polite and efficient!"
