If I had to pick a place to stay in Berlin, I would pick Claudia's house again.
Since I got there she explained everything with details, showed me the house and common spaces, everything was clean and organized.
The apartment is located in one of the most beautiful spots of Berlín, there's a lot of coffees, restaurants and bars nearby, and it's also really easy to get there using the subway.
Claudia has a lovely family, they were always there to make some suggestions/recommendation in terms of what places to visit and how to get there.
Thanks you so much, what an excellent host!!
