Reviews

Former tenant·9 months ago

Great Time Living Here

Pros

Super genuinely cares, building is reasonably priced and well kept, regular renovations for tenants who renew, tenants tend to stay for a long time, central air, so close to train

Cons

AC/heat bills can get high. Walls inside the rooms were thin

Former tenant·10 months ago

Good for the price

Pros

This is a great unit for the price of rent. Given the neighborhood is SO expensive and popular, the rent here is a steal. The building is clean, the landlord is responsive, and the neighbors are nice. The living room is MASSIVE and the apartments are overall set up well for guests and entertaining. You will be supremely comfortable here.

Cons

Unfortunately, the apartments could use a facelift. While there are crucial things like central air and heat, the bathrooms and kitchens are outdated as well as the flooring throughout the apartment. A little love could go a long way.
