Staff excellent - friendly, professional and very helpful. Room very good, clean and comfortable. Good, clean bathroom. Parking is a little awkward, particularly if you have any physical limitations: public car park is fairly good alternative [paying for parking was the only surprise.].
Breakfast was good, with plenty of choice. Location right next to Watford Junction Station is very handy for city and regional access and connections.
Would definitely recommend and stay again, particulary good for such as Elstree Srudios or Warner Bros.
