The best bit of Rome is the way that if you don't want to go to the tourist spots, you can just turn any corner and the random church you find will be more impressive than any that you have ever seen anywhere, anyway.
Also, even for Italy the food is really good, with easier restaurants than e.g. Tuscany and very child friendly.
Yes, the Haydn Box by the Schneider Quartet is very good.
I am not generally a big fan of performances by groups using Period Instrument string quartets. However, having listened to so many many string quartet recordings by various groups using modern strings, I decided to give some of the Period Instrument groups a try. So am now turning my attention to Haydn Quartet recordings by these 3 groups.
Festitics Quartet
Buchberger Quartet
London Haydn Quartet
