I saw short reviews of this hotel around up in the charts for best value for money, as I like to scour for hidden gems. I was not disappointed. It is situated under the castle exactly in the centre but with great prices. The staff were excellent and very informal and relaxed but still willing to pander to your needs. we got an apartment for four people and it had all the trimmings. Wooden floors and antiques in an old building - and free breakfast to boot.
