Staying at Ella's place was very easy! She is very nice and hospitable and the house is cosy and very warm :-)
She had sent me extremely accurate directions in advance to get to her place so that I could get there so easily.
She left a shelf in the fridge for me as well as milk and tea for breakfast.
The place is actually just a stone's throw from metro /train station and you can easily walk to Gamla Stan (old town). The nearby area is as well very nice and safe with lots of shops and restaurants.
Ella also adviced me about some more things I could do/see in Stockholm. I enjouyed my days in Stockholm and at Ella's!!
I would definitely recommend to choose her house.
