Hayes is a rather run-down and unkept area, so it's good to see that the Premier Inn stands out as being clean and comfortable. The staff are very welcoming and interested in their customers beyond the standard greeting and the housekeeping ladies are friendly and helpful too.
I had a double room for single use and it was spacious and comfortable. The bed was one of the best I've slept on in a hotel so I got a good night's sleep. The rooms are well sound proofed so there was very little sound from outside and the other guests didn't disturb me either.
We had breakfast in the Beefeater next door which, for a chain restaurant, was one of the best cooked breakfasts I've tasted in a while. And there was no pressure to be off the table so we probably spent a good hour and a half over the meal.
All in all I'd say this is a great place to stay if you need to be in the area. The only downside was the lack of a lounge/bar area, so we just congregated in one of the bedrooms.
