Ignore the three stars on the hotel's entrance. This is really a four-star hotel, and it certainly deserves its high rating on TripAdvisor.
Yes, the façade is modern. It more than makes up for it with its amenities and service. I booked a double room - upgraded to a spacious suite at check-in. The suite was great, very comfortable, excellent sound isolation. Very clean. Excellent bathroom amenities (shampoos and soaps in different small bottles).
The service was top-notch. The staff were friendly and helpful at all times, without exception. I had a cappuccino in the breakfast room in the morning on day one, and this was instantly remembered and offered without my asking over the next several days. The breakfast itself was very praiseworthy: a buffet with a lot of choice, very filling and tasty.
Location, it is true, is outside the old town, but it's only a ten-minute walk and a pleasant one at that. Conveniently, it's also ten minutes away (walk) from the train station.
Bottom line: can't recommend the place highly enough and I will not hesitate to stay here again if I am ever back.
