Coincidentally, I was in this building just two days ago performing a BPO. You have asked about the Portobello Complex but I believe the building in this listing is called the Fourth Street Lofts (at least this is the name on the building). It is a revamped warehouse with mixed use spaces. There are businesses and a restaurant on the ground floor with the condo units accessed through a secured door. I was also in the building about a year ago and both of the units I have seen were fairly large loft style units with somewhat large, open living space and an open loft space for the bedroom. The area has a number of properties similar to this one with some being re-worked and others being significantly newer buildings. There is a lot of foot traffic (I was there at lunch time) with plenty of restaurants with outdoor eating spots, coffee shops etc...
If I can be of any further assistance, please feel free to let me know.
