We recently went to Stockholm for a friend’s wedding and I do have to say everything was absolutely lovely. We stayed at Hotel Rival, which is known not only for being Stockholm’s first boutique hotel, but also for one of its owners: Benny Andersson of Abba.
The rooms were excellent- the beds were superb, flat screen TVs (you can check out movies from the front desk) in each room, minimalist bathrooms… it just felt like a luxury hotel. There are tons of shops and sightseeing to be had within walking distance around the Södermalm district (Stockholm’s got good design coming out of its ears) and you can’t miss the sense of history with all the cobblestone streets and buildings that have survived hundreds of years. I recommend a visit if you ever get a chance.
