After staying for five days I found the Heron to have well equipped standard rooms with comfortable beds, a good desk, reliable wifi and an good if limited choice of TV channels.
The Bar, dining room and coffee shop were all attractive, but ruined by the clear problem of inadequately trained serving staff. In the case of the coffee shop there was also a lack of sufficient waiters and short order cooks, whilst there were excessive but badly organized bodies in the main dining room. I suggest that the hotel should look to recruit a short term advisor to retrain the front of house, and advise the management to dismiss supervisory staff unwilling to "get with the programme". I suspect that much of the problem comes from the places historic reputation as a "hire rooms by the hour" establishment.
