hello, walking distance from Saint Stephen Platz, or 2 stops with metroline 3 (U3) to Volkstheater

There are no restaurants in the park but there are small pavilions. But there are several in the area around the park. Espescially on the other site of the sissi museum in the centre of old town.

I doubt the roses will be blooming already in April, but it's a LOVELY park anyway, and worth a visit!

I think depending on the weather but a little to early to bloom but lovely little park

Sorry don't know about roses, but I expect that there will still be beautiful flowers there.
