I need to book 5 nights' accommodation from 1 April to 6 April 2010 - yup, you've guessed it, the Easter weekend which is why I'm starting now - for me, OH and FIL near the Opera House on the Bismarckstrasse, because FIL is an opera buff and we are treating him as he's seen all Wagner's operas except Rienzi.

I'm looking for a comfortable but not luxury hotel 3* or similar with rooms with ensuite facilities, in either easy walking distance or easy U/S bahn distance. I'd hope to pay less than 100€ a night for a double and less than 130€ for a single, but perhaps I'm being unreasonable for this area of the city. I've heard of the Leonardo nearby, but could anyone comment on it or advise me on other hotels?

Very much appreciated. Thanks in advance for your help.
