although it's not in the city center Kerstin place is very close to a tube station that leads to the city center in 15 minutes. my wife and I bought the 72 hour public transport pass and it was absolutely worth it. the room we stayed in was huge. the toilet and the shower are in separate rooms, which I don't particularly like, but that's also not a deal breaker. Kerstin and her husband are lovely, they even let us use their washing machine and dryer. I would recommend Kerstin place to anyone staying in Stockholm !
