Excellent room, very spacious and great views from the tower. Very modern hotel. Only thing was it didn't have a bar so you had to leave the hotel to go for a drink. Staff were friendly and welcoming. There was an issue with parking though - we paid the fee at the hotel and then were charged again by the car park provider as none of the tickets the hotel provided to us worked (so cost over £70 for parking in the end). We were also stuck at the parking exit gate with a queue of cars behind so had no choice but to pay again. Also car park is a walk away and there isnt an easy place to stop near the hotel to unload luggage.

This hotel offered a beautiful and spacious room that is ideal for large families or groups. We only stayed 1 night but would consider this a nice option for week long stays. The people that work there are genuinely kind and welcoming.
