I came to Stockholm with a friend and we had a very nice stay at Tomas's place ! You'll only have to walk for 5 min to the subway which can bring you to the city center in just a few minutes. The apartment is nice, clean, located in a calm and beautiful area, and Tomas was always available. He was very accomodating and also sent us some good recommendations for bars and restaurants which we absolutely enjoyed.
I definitely recommend Tomas's appartment for your stay in Stockholm !
