Is Tel Aviv good place to stay in?

That depends. For what? I wouldn't commute from there to Vienna.

It's a great town. Excellent nightlife, the beach of course, and my favorite Jewish Heritage Museum on the world: Beit Hatfutsot.

The other two big cities Jerusalem, and Haifa also have there charms so ideally you should stay a bit in all three places.

Yes...it’s definitely a step up from Nuseirat.
