I have stayed there last year, there wasn't any upgrade as I remember. The wireless signal in room were so poor, you can't work more than 2 minutes continously. When complainted, they said customers who want to use wireless network should tell them at check in, so they may give a better positioned room. That's "the place to meet" and we need to remember to tell them "I've got a laptop and need to use wireless network" - I don't ever remember I need to declare that at any other hotel.
The room were very dated, although spacious. The bar were very small and really out of date. The good thing about it is that it is centrally located, and easy to walk around the city centre.
Their manager said that they have just been purchased by another company and will start a renovation shortly. I am not sure whether they've done that already, so maybe still a construction site.
I will not recommend that hotel to anyone, unless you plan to spend every minute outside the hotel except sleeping.
