We stayed at Soren's place for New Years in Barcelona, and it was perfect!
Ideal location - walking distance to all of the main sights.
Clean and tidy, with lots of personality, and a big terrace with a great view. Kitchen was well-stocked, so we could cook food when we didn't fancy eating out.
The only thing I would mention is that it is on the fifth floor of a building without a lift - so getting in and out with heavy bags is not completely easy. But the view when you get to the terrace makes the climb totally worth it...
Highly recommended, and excellent value for money
