45 Y/O American visiting Cardiff for the first time for a few days in October. Will be alone. Not into bars or clubs. Into lots of walking and museums and sights. Could someone please recommend a quiet hotel (not near bars or nightlfe) but within the city so I can walk everywhere. Not looking to do anything special and have no agenda - just whatever moves me! Plan to arrive in Cardiff by coach from Heathrow. Days of the week are very flexible too. Very content sitting in hotel room, it just seems like a waste.
