What are the best "walking" neighborhoods in Indy?

[Laura Bender]

Of the top of your head:  

1) what Indianapolis neighborhoods are best for someone who wants an older home with character in a well-established area that's within walking distance to lots of trendy shops, restaurants, gallaries etc.?  

2)In your opinion, what are the best "up and coming" neighborhoods --those with a lot of recent rehab/fix and flip activity?

Thank you!
