We had a good time at Rasmus' really awesome flat. The place is huge and we had plenty of space for 6 people 2 kids, 4 adults)
Check in was easy. The flat is very well equipped with everything you might need.The kids loved that they could play with all the toys.
The flat is very well located, with a bus right around the corner and the metro close by. The street is small but a bit noisy in the evenings - not terribly so, but not peace and quiet either.
The only thing one can criticize is that the kitchen might not fulfill a neat-freak's expectations. An extra scrub here and there would not have hurt.
But overall, very nice place and definitely recommendable.
