Ewa is a very nice and hospitable host.
When I arrived she greeted me at the exact pre-established time of the day and prepared breakfast for me every morning so that I could enjoy my time visiting Stockholm at fullest without bothering to spend a lot of money in the very expensive Stockholm.
Ewa also suggested some of the main attractions present in the city and I did make good use of them.
Her apartment is close to the city centre (about a few hundreds of meters from the closest tube station) and is very clean.
I totally recommend her place for young people wanting to visit Stockholm for a few days.
