I stay at the Glendale regularly to visit my daughter and granddaughter who live nearby. It is a lovely hotel above an Italian restaurant with very convenient access to Penarth train station with regular trains into nearby Cardiff.
It has both single and double size rooms and I usually choose a single. The rooms are well appointed with rather basic shower facilities, tea & coffee etc. a very nice full cooked English breakfast is available (extra) and of course there is the very convenient excellent restaurant downstairs. The owner/manager is very friendly and chatty.
Have stayed here a few times and find it very comfortable, both the singles and doubles. Really lovely staff and great location.
What a lovely little hotel. We arrived quite late on a Saturday and we're welcomed by the friendly owner. Our room was clean and comfortable with a cute, old fashioned door key. We had a drink in the bar but didn't eat in the restaurant, although it did look lovely.
