We’ve stayed many times at Hotel Du Vin Brighton and always enjoyed it. The staff continue to be excellent, going out of their way to be helpful, often unprompted.
However, considering how expensive the hotel has become, it could be said to be sitting on its laurels. Our room didn’t appear to have been refurbished for a long time. The room carpet was stained (probably not a good idea to have a plain pale brown carpet in a hotel room). The bathrobes had shrunk so much mine wouldn’t fit around me. You would expect better of a hotel charging around £100 a night, let alone one charging £300 for a Deluxe but still fairly small room!
Breakfast in the restaurant was excellent, then again at £24 ahead you would expect it to be. Dinner was only so so. And perhaps the lack of diners on the Thursday evening was indicative of the amount of good choice that people have in Brighton.
Finally, Parking has become a nightmare in Brighton. Local car parks are £40 for 24 hours. If you can, park outside Brighton and get the bus in, or use Just Park. I managed to find a spot 15 minutes walk away for £72 for the three days we were there.
