Summary: Lovely hotel to come back to after a long time. It’s still the same. Nicely sized rooms with a huge bathroom with shower and bath. Wonderful staff who are courteous, professional and always helpful, willing to going to extra mile to make sure our stay was comfortable. My only comment is that the hotel is currently upgrading and refurbishing so the spa is closed although guest rooms have been opened up as an alternative. There is drilling noises in the background most days throughout the day, but I appreciate all this is necessary for the hotel to be maintained and improved.
