We stayed at William's place in the Old Town area of Stockholm (Gamla Stan) for 3 days as part of a family trip and had a great time there. The location is excellent, as it's right in the middle of restaurants, bars, stores, and museums, and it's very easy to get around the entire city from there. The loft is clean with great views of the city, comfortable beds, and an excellent coffee machine. Everything was as described in the Airbnb description, and William was very responsive the whole time we stayed there (we had a small issue with the keys at first, which was my fault, and he responded within minutes and had us ready to go).
