Top Gwynedd Hotel Reviews

Celtic Royal Hotel & Spa

8/10 Good

"Hotel reception is good. Hotel room is not good because smells and very poor maintenance windows curtains and water taps not working properly."

Aberdunant Hall

10/10 Excellent

"The hot tub trailer that we had was beautiful. We had an amazing dinner in the restaurant after our arrival.We enjoyed the hot tub in the evening, the rain hitting the metal roof was so relaxing. The bed was incredibly comfortable.The experience start to finish was wonderful and we will definitely come back for a longer duration next time."

Penhelig Arms

10/10 Excellent

"Received a warm welcome when we arrived and were directed to our room. We stayed in one of the Suites which are in a separate building from the pub, with outside steps leading down to the pub. The car can be taken up a steep slope where there is dedicated parking for each Suite room. We enjoyed a lovely cooked breakfast each morning, which was consistently delicious for the 3 days of our stay. Pre-booking is advisable for evening meals, and these were always lovely. Our Suite room was huge with a sofa (can be turned into a bed and would be ideal for a family) chair, dressing table, plenty of storage space, drawers and hanging. Lots of plug sockets. TV, tea and coffee making plus a fridge. It was cool weather during our stay and the bathroom had a heated floor which was welcome. Large walk in shower plus separate bath. Lots of windows so the place is bright and airy. Balcony with table and chairs with wonderful views overlooking the Estuary. Comfortable bed."

The Royal Victoria Hotel

10/10 Excellent

"Just back from a 2 night stay at The Royal Victoria Hotel and after having read some very mixed reviews, I didn't really know what to expect, but the place was absolutely fine. Location was literally just across the road from the start if the Llanberis path for Snowdon or the railway if yiu wanted to get the train up. We found the staff, room and breakfast all to be ideal. Our only little downside was the shower tray filled up with water but we let them know when we checked out. I had booked the coach house, but upon arrival found we'd actually been put in the hotel, so was even better. There were tea/coffee making facilities in the room which you could get more of at the reception, an iron, ironing board, hairdryer, fan and a sofa alongside a superking size bed (2 singles pushed together). I would stay there again if I ever went to that area and its the perfect location for sightseeing and climbing Snowdon."

Ty Glyndwr Hotel Bangor

8/10 Good

"Hotel name is not visible from the street. Parking on site was appreciated. Bar staff were friendly and helpful. The restaurant was 'open' but the cook was not there. After a while they reached her by phone and she would be there in 15 minutes, and was told to take our orders and I paid for two 'specials'. After arrival, the cook/owner(?) came out and chatted with several locals and then brought her dog out to visit with a guests dog. Later she came out with a hairnet on making me optimistic. We had an overnight flight and a long day to this point. One couple came out of the kitchen with full meals. We watched them eat and take home the leftovers. Keep in mind no one had ordered food before us. Next, another couple were served, and ate their food. Clearly they noticed we had been waiting longer. After a while my food came out. 10 or 15 minutes later, my friend was told the cook read the order wrong and was now going to remake her food. By now I was finished, the bartender offered my friend a glass of beer, same as we had on arrival. By then she was past it, we were tired, hungry and angry. Eventually she got her food, and ate alone. Our meals were not worth waiting ..and waiting for. We were there for hours. The cook coming out and apologizing would have been a nice gesture. The next night we went elsewhere for food."
