The rooms are very warm and carpet was torn in a few places. The toilet lush was hanging off the unit. Staff were pleasant but more needed on desk at check in time. Was convenient for what we needed

8.4/10 Very good! (613 reviews)
The hotel could be amazing but unfortunately it is now dated and needs to be refurbished. The standard twin room does not have an overhead shower and the room was dated and shabby. There was no bottled water as stated either. The room was also very hot and they do not provide fans as standard. The pool is lovely but does need a little TLC and the showers in the changing rooms are extremely hot. As is the general temperature of the changing rooms. There was an issue with scolding hot water from both taps in the sink and staff did sort this fairly quickly. I would not the hot temperature water in the rooms is very hot and should have a warning note. Also you are on a busy fast road, which is audible and tricky to pull onto. The staff were lovely and very helpful.

Room was very hot and I didn’t want to open the window as it was on the ground floor. Everything else was great though, staff were lovely and really helpful, pool was really nice and the room was clean.
