Ursula was kind and I am sure she is a good person.

Be careful about the apartment however!
You will have to share a tiny bathroom and kitchen with other 7 persons! (it's ok to share a bathroom with 1 or 2 persons more, but other 7 it should be written in the description! )The room is around 20 square meters, you cannot use balconies and you cannot lock it.

I paid more than 100 euros per night, for the same amount of money you can get hotel rooms much better.
