We stayed at the apartment while my company exhibited in an event in CCIB. The CCIB is nearby, a mere 5 minutes walk, so the location was just perfect. On top of that, there is a metro station nearby, making it really easy to go to Ramblas, Barrio Gotico, etc.
We were greated by Vaishali husband and daughter. They are very friendly, warm and helpful people.
The apartment itself is very clean, with three spacious bedrooms and a nice kitchen.
I strongly recommend it to anyone going to Barcelona on work or holiday.
