This is a great place to stay. It's clean, quiet, very thoughtfully decorated and had everything we needed. It was very walkable to the old city and we had no problem orientating ourselves. There were grocery stores within a 10 minute walk as well.
The elevator is a bit of an adventure, but not in a scary way. We got stuck once but trust me, Hotel management has clear instructions how to navigate it, and if you follow them you'll be fine.
It was our first experience with not checking in through a front desk, but it was painless and easy. Management responded to my emails without delay, and the whole experience was transparent and stress free.
One thing I would recommend is that you not use the baggage storage app that the hotel offers and store your luggage at the central train station which is at most a 15 minute walk away. The reason I'm saying this is that the app won't tell you where the storage places are located until after you've booked, and you waste a lot of time trying to locate one. Also, the storage place that we booked asked us to pay for luggage insurance on top of the storage fee - which made us question how secure it was in the first place. Save yourself time and grief by renting a locker. We came off a cruise very early in the morning, took a cab to the station, checked our bags and walked from there.
It was a great experience in a wonderfully beautiful city, and I look forward to my next stay.
