We stayed for three nights in August. The views of the bay are fantastic and every room gets one so I understand. However the rooms are very dated and are not what we'd consider 4 star. There was also no aircon in our room, which any other time of year would probably have been fine, but the evenings were warm and to cool the rooms down we had to open the door to the balcony. Unfortunately this means you have to put up with both the noise from the nearby road and the possible smoking of your neighbor on their balcony.
The service and the restaurant were fine and we were able to park, although spaces are limited. We looked at the pool and the wellness area and was pretty underwhelming.
The hotel is a few hundred metres from the Italian border and we found that the better eating options were on that side, particularly if you are prepared to walk around the bay (its quieter there). You can get to Lugano by train (almost stops outside the hotel) or by ferry (although limited service to the bay). If you do go try and visit the little village of Morcote, it is truly beautiful and relatively untouched by the tourist crowds.
If the view from your balcony is really important and your not bothered about the room or being slightly away from bustle of Lugano then its fine, if you're looking for genuine 4 star quality then perhaps look elsewhere.
