I use an A6000 as my 'travel' camera - when on days out with the family, general holidays, etc.
I have the two kit lenses (16-50, 55-210) and the 50 f/1.8 OSS, plus a Neewer NW-320 flash (which is the same as the Meike MK-320).
That lot fits in a small shoulder bag (with spare batteries and SD cards), or if I want to carry a bit more I have a small camera backpack (50% camera gear, 50% general gear) which allows me to add other bits and pieces such as a ND / Grad filter kit, charger, etc.
The 16-50 is a bit prone to flare, particularly as it does not have a hood (I have a small 3rd party one which screws into the filter thread and improves things, but care is still needed), but both the kit lenses are fine for general use, and can produce superb images when stopped down.
The big benefit of the 16-50 is how small it is when powered down - I can put the A6000 with 16-50 mounted in my jacket pocket, making it great for just wandering about with.
In terms of ISO, images are fine up to 1600, and usable to 3200.
AF is fairly good, but you will suffer from lag in the EVF at high FPS, making tracking BIF tricky, for example.
Would I recommend one - YES, you get a lot of camera for the money, in a package that's easy to take wherever you go.
