Stockholm, the apartment and the hosts are very lovely!! We enjoyed our stay with Mikael very much, he was always reachable by phone and very helpful with everything we needed!
The apartment is great, especially if you like to cook small meals because you don't want to or can't afford going out all the time.
The location is awesome as it very very central and also has great shopping possibilities. The one and only downside is the noise, which can keep you from sleeping. But it is definitely worth it :)
