Visiting Berlin - what neighborhood would be best to stay with 3 year old.

My husband and I are visiting Berlin for a week in May with our almost 3 year old. We can’t seem to find any recommendations on what neighbourhood to stay in with a toddler in tow. We’re currently booked at 2 places - Adina Checkpoint Charlie and Downtown Apartments Mitte. Would either of these neighbourhood a be decent with a toddler? Any other recommendations?

Thanks! :)
