I lived in the building next door (Corner Lofts) last year. Shockoe Slip is a great choice for living car-free. It has good transit access and is walkable to restaurants, small businesses, and a farmers market (on certain weekends). The closest grocery store, Farm Fresh, is about 10 blocks down Main Street. The canal walk is easy to access, and leads to green spaces and parks on either end.

There are some annoying aspects to the location, so just as a heads-up:

• it can get pretty loud, especially if you get one of the units facing Main Street. For the Exchange Place building, I would look into whether there's good soundproofing between Square Code Fitness and the apartments above because I could often hear the music from the sidewalk/parking lot.
• the parking lot and the alley are kind of gross, people don't pick up after their dogs and the trash isn't collected often enough so some of it ends up outside of the dumpsters. I would stick to the lobby entrance if possible.

Overall though I would say it's a good area to start off in and get to know the city, it really facilitates exploration and can be good deal with the utilities included.

This turned into a pretty long comment, but I hope it's been helpful. Feel free to reach out if you have more questions about the area!
