The location is fantastic! The neighborhood has everything you need, a coffee shop, bakery, grocery store, liquor store within few minutes walk and the public transit connection with all the touristy areas as well as bus/train stations is so convenient! Carolina is really nice and responsive. She responds really quickly and is very helpful. The place is very functional and so clean! I worked out on the floor everyday and didn’t see one speck of dust anywhere including UNDER the kitchen counter! I would definitely recommend Carolina’s to anyone staying in Berlin. Ps: the wifi was super quick too!
