I had a fantastic stay at this hotel. The room with a great mountain view was incredible, and the kitchenette was spotless. However, the closure of the restaurant was a bit inconvenient. The service was top-notch at the reception desk, and the staff ensured we were well taken care of. The location in the city center made exploring easy, but there were a few activities we missed out on. Dining was not included, but the handmade pasta was delicious. The facilities were modern and well-maintained. Overall, a great value for money.
