Federico's apartment was great! It was clean, cozy, and just as described. We were three people and comfortably fit for sleeping and hanging out. The beds were comfortable and the apartment had everything, like plates, cups, and towels. Getting around with public transportation was very convenient. The tram is about a block away, and so is a tasty vietnamese restaurant (with good prices). A convenience store is also within a few blocks (for picking up drinks :)).

Federico was a very attentive host. He was patient when we were delayed and checked in late, and was flexible with our departure time. He checked in with us throughout our stay and made himself available to give us insider tips on where to eat and things to do in Berlin. He truly went out of his way to make sure we had a great stay in Berlin.
Thanks Federico!
