Stayed 2 nights in the Granduca only 30 days after it opened apparently. Modelled on an Italian palace, the hotel suites are clearly aimed at the longer term visitor. I had a suite on the 5th floor with kitchen, dining space and lounge in one open plan style. The next room was the bedroom, a l-shaped space with a large, high bed and a desk area with cable network access. Off there were two other rooms, a dressing room with a very small safe and the other room was the bathroom. The Granduca aims to live up to the luxury of a palace and it is clearly a cut above the usual hotel suite. The bed was one of the best parts - one of the most comfortable I've ever slept in. However, some of the decor is clearly 'faux' and the acrylic bath let down an otherwise deluxe feel. The only real quibbles I'd have with it were:
there was only one wastebin in the entire suite (in the bathroom)
the shower temperature fluctuated and took time to run warm
the safe was too tiny to put anything other than papers and other small items.

On the plus side:
Large plasma HDTV in both lounge and bedroom
Individual environmental controls in both main rooms
Fully-featured kitchen
A home-from-home feel in the decor (books, pictures, objects, etc.)
Great toiletries and the thickest towels I've ever used
Complimentary wireless (throughout) and wired internet access from the desk area in the bedroom

I didn't eat at the hotel at all, so can't really comment on that aspect. However, the options available appeared to suggest that there was an assumption that guests would either self-cater or go out.

A really good longer-term option or for self-catering. The hotel offers up to 3-bedroom suites, so potentially a great option for families. The area is about 5 minutes drive from the Galeria (huge shopping mall).
