The Miss Clara hotel was wonderful. Very clean, beds were extremely comfortable, and lovely bathroom amenities. The woman who checked us in was also very helpful. Unfortunately, a second woman at the concierge gave us inaccurate information regarding Christmas markets - the purpose of this trip was meant to be very festive and visit as many markets as possible. She instructed us to go to the open air museum market (our trip took place mid-week), however when we arrived... after a 1h walk... we found out that this market is in fact only open on weekends which was quite disappointing. The only other market that was in Stockholm was as very small in Gamla Stan - nothing special in my opinion, however that area of the city was quite nice to walk around in in general.
I also would NOT recommend the Miss Clara restaurant to anyone who is a vegan. The server told me he would ask the chef to create something for me in the kitchen, as there are zero vegan options they normally offer there. What came out was honestly quite terrible - after complaining, it wasn’t removed from the bill, despite me only having taken 1 bite. I went down the street and ate lunch next door at a much more suitable restaurant restaurant.
Overall, aside from the Miss Clara hotel, I wouldn’t recommend Stockholm or return in the future.
