If your cross street is Maple it’s definitely a little bit of a seedy area but nothing to be too concerned about. You’re right down the street from Bagel Cafe and Restoration Cafe, both great breakfast spots. Pizza by Rocco up the street has the best pizza in the city. You’re also walkable to Elm where there are various bars, cafes, and restaurants. Walking home at night from Elm I would keep your guard up and if you’re really worried you can just hop in a quick uber. There is some beautiful nature in and around the city and an hour north puts you in the Lakes Region and another 15-30 minutes in the heart of the White Mountains. 45 Minutes east is the Atlantic Ocean. If you’re not into outdoor activities there’s plenty of other things to do in Manchester, and Boston is less than an hour away if you’re looking for a bigger city experience. I was hesitant to move to Manchester in my mid 20s as well but I’ve been here over a year now and I really think it is a great place to live.
