I am not familiar with Hotel Excelsior Splendide, but if you want to spend a full week in Bellagio, as we did earlier this year, you might want to consider staying at Residence L'Ulivo Apartments. This is a residence of 13 apartments in the grounds of the Grand Hotel Villa Serbelloni. http://www.villaserbelloni.it/

There are apartments of different sizes, each with a small kitchenette and a living/dining room. They are serviced every day and are spotlessly clean and most comfortable. Residents of the apartments have full use of all hotel amenities such as the health club, and the hotel/residence is in close walking distance to the shops and restaurants in the town, in fact you won't want to use your car in Bellagio at all.
