We loved our stay in the apartment! It's in such a great location- we were able to walk all over the city from Gamla Stan. The apartment itself was so clean, comfortable and welcoming. Yes, the front room can be a little loud (my friend stayed in that room and only heard noise one night out of 7), but the back room is very quiet. Just use the white noise app on your phone and you'll be fine. We will definitely recommend this apartment to friends visiting Stockholm. We loved it and would definitely stay here again. Communication with William was seamless. He always immediately answered texts or emails.
