I stayed here recently for a family trip to the UK and was pleased with the hotel, both the rooms and the service. Very tidy, well located, and parking was much much easier than at the Premier Inn on the other side of Bournemouth where I also stayed recently.
Rooms were big enough, bathroom was well laid out, but it is clear that this is an older hotel just recently taken over by the chain, thus not as fresh as some of the newer purpose-built Premier Inns. Nonetheless, the short 3 minute walk to the beach and boardwalk that runs in between Boscombe and Bournemouth piers is GOLDEN!!! Gorgeous area, and this alone should inspire people to book here over other Bournemouth spots. By the way, it's also only minutes to the train station as well as the A35 Ring Road if you are travelling by car.
One little let down was that the breakfast at the Premier Inn Westcliffe is a bit better, but that's my bug, and shouldn't sway your decision. But perhaps the East could steal some ideas from the West!
