Good breakfast, clean room
Bed was a bit small
The room was clean and comfortable. Breakfast was nice.
There was no O2 or Vodafone mobile signal inside and no phone in the room. The wifi was unusable. I wouldn't recommend for business travellers needing communication. Reception doesn't open until 4pm and closes at 9pm. This wasn't clear on my booking so I had to wait in my car for an hour upon arriving. I was told not to venture out in Merthyr at night and the guest house only serves breakfast so I brought my own meal for the first night. But I wasn't allowed to use their microwave despite offering to pay for the 2 minutes required. I got called away a day early but was still charged for the last night even though I was the only one staying there.
Staff was very friendly
menu should be more varied
Great Location Warm and happy staff Very relaxed atmosphere
Had all the facilities needed and looked like a lovely place to spend a few days. Unfortunately we were just passing through.
Homely welcome from Molly, the views and easy access to good walks and centres. Everything was spotlessly clean and cared for.
It is great place for star gazing.
If the open time of the lounge can be longer.
we had an amazing time. Staff were friendly and helpful. The b&b was super clean. Would high recommend.
Comfort and good breakfast and staff.
Breakfast was tasty and the beds were super comfy. Really enjoyed the stay and very reasonably priced as well.
Modern room and facilities, comfortable bed, lovely dining and breakfast. Friendly staff.
TV reception was unacceptable and when I reported this next morning, the lady seemed dismissive of my comments. Reception in the lounge area was fine so problem was internal to the guest room.
room was clean and spacious, staff were very friendly and approachable, breakfast was really good, parking good 10/10
there is nothing I did not like
Clean room and good breakfast
Mobile phone out of range Wi-fi very weak Television was even breaking up! This made the evening/overnight very remote for a business traveller as nearest town some miles away. Probably ideal for walkers/bikers but definitely not for workers!
All as described by my ratings
Ensuite facilities, great location overlooking the lake and only two miles from pub offering good food, large bedroom, great Welsh Breakfast. Location also good for visit to Castle at Merthyr
traffic was very fast on the road but only an inconvenience when we walked to and from the lake.
Lovely breakfast - friendly cheerful staff. Lovely location with garden overlooking the lake.
Not really enamored with the electric perfumers - found them a bit overpowering
Fantastic location, great view and very helpful staff. Very good experience, will be back!
Would definitely stay here again. Clean and spacious rooms, amazing location. Quality of breakfast and service was outstanding with friendly polite staff.
gave the idea you could see lake.
