Irene has been a very nice host.
The house was really fine and clean and my stay of 3 night has been super comfortable. I don't think I can give to Irene any particular suggestion on how to improve her offer since any detail in her house reflects her choice of offer.
Beside the place and the comfort of my stay, Irene is a really positive person: she likeed to speak with me but has been really discrete. Since I will settle in Munich I'm not sure I will stay again at Irene's, but for sure I will suggest her accomodation to every friend who will come to visit Munich.
Thank you Irene :)
