I 100% recommend staying here. A lovely apartment. Very nicely decorated and furnished - just like in the pictures. The location is excellent - less than 10 minutes to Gamla Stan by foot and surrounded by many interesting shops and delicious restaurants and cafés in Södermalm. (We really recommend Cafe Fåtöljen - excellent coffee, juice, and food.)
The dining room table doubles as a perfect work space. The sofa is really comfortable. And the heated floor in the bathroom is absolutely awesome. Everything was really clean. Lots of hot water in the shower. Nice soap and shampoo products, extra towels, sheets, blankets, etc. Warm, relaxing lighting and enough closet space and hangers.
The second bed (sofa bed) is not the sofa, it's an armchair right next to the bed. So, the place is suitable for two good friends or a very close family of three. On the plus side, my friend said that the pull out armchair bed was really comfortable! The bed itself is good size. It is a bit on the soft side, and the pillows are thin. It takes some adjusting to get used to the Hilton lobby being directly across from the windows (as we'd read in previous reviews). There is no privacy except with the curtains drawn. It got a bit chilly when the temperature dropped to 20°F - the heaters couldn't quite warm the place.
Nicol was an AMAZING host who helped me find a copy/print place in the area when I needed it. Communication was absolutely fantastic and friendly. The building is also quiet and has a friendly hotel kind of vibe.
Every place has pros and cons - if this one suits your needs, go for it without a second thought! My friend and I had a great stay here and a lovely time in Stockholm.
