I will be listing a very large 1-bedroom condo in The Strand (aka 429 Somerset St West) next week. The unit comes with parking and is close to 800sqft in size with excellent storage, great space for entertaining (the Seller has easily managed parties of 25 people) and occupancy as of September 1st.
One bedroom condos in downtown Ottawa have been pretty scarce this year, so if you aren't working with another realtor, please feel free to get in touch and arrange a visit.
