Former tenant·5 minutes ago

Good neighborhood, close to B/Q

Pros

Neighbors aren't overly loud, though sometimes I hear them when I'm in the lobby. Closeness to the B/Q trains is amazing, and I love there being cafe's, grocery stores (expensive but convenient), and laundry nearby. You are allowed to paint the apartment if you paint it back at move out. Pet friendly. Good price for the area.

Cons

No laundry in building. Sometimes maintenance takes a bit to get back to us. Pest control doesn't seem to be on a schedule and they will not reach out to spray your apartment. You will only get pest control if you happen to bump into them. The buttons to buzz in are unlabeled and the key fob to get in doesn't work when it rains, if you know the code to get in its okay.

Advice to the owners

I wish maintenance would respond to issues quicker, and that pest control would reach out to us when in the area so we could let them in

Overall time at the building -Former tenant

Pros

Used this site for my new apt and so wanted to write here to help others - I lived here and have dogs. I like the convenience to trains and had a spacious 1 bedroom. Laundry is just a block over and so is the supermarket Friendly neighbors and overall good experience with no issues . Payments online are easy Goodluck !

Cons

Hallway can use a paint but looks like they’ll be doing that soon
