I'm a realtor fully familiar with the building you inquire about. I would recommend the 1 bedroom units as a better bargain than the junior four units, as they are almost identical in size. Oddly the 1 bedroom units there have more spacious livingrooms. The main difference is that j4 has a small room enclosed by a door, it is an actual room. The 1 bedroom units have the same space, but as an alcove without the door. Either way the space can be used as you please, and is more modern without the door. Many use that space for dining as the j4's don't have a dining space. For a difference of $50,000 I would suggest the 1 bedrooom unit.
