This is a great spot convenient to so many amazing parts of Stockholm! The Slussen t-bana stop is a two minute walk away and Old Town is a very easy walk or scooter ride. The apartment itself is cozy and lovely, had everything I needed. Check in with a key code was a breeze.
The only watch out I do want to mention is that there are quite a few stairs to get up and no elevator—this was fine for me but would not recommend for someone with mobility issues or a lot of heavy luggage.
