We had a great time in Barcelona staying at Gunnar's place. The location was perfect and the space was well suited to a large group and for having meetings there throughout the week. The only downside was that the garden was a bit overgrown and not well cared for when we visited, so we did not make use of that space. Take note that if you plan to use all 6 bedrooms, one of the bedroom's entrances requires passing through other bedrooms.
