Feels like an studio-apartment away from home. The hotel-model that SMARTments uses looks a lot like the "studenthotel" we have here in the Netherlands and works great for short stays or vacation. Be sure to bring your own toiletries (you do get towels) as it's literally a tiny apartment for yourself, where you use your own card key to enter the building and your apartment. As for the location, it's near a station where you can get a S-bahn for quick travel to other parts of berlin and tram station for a short trip to de center.
