Alan and Kasia's place is fantastic - the apartment was spacious, clean and in a great location. Check in was handled by yourwelcomeberlin who were there to greet us at our arrival and made check in a breeze. The tram and s-Bahn is a minute walk from the apartment where you can easily travel to the different parts of the city. Alan and Kasia also had a very helpful book with tips on where to visit, eat and drink. I would definitely recommend staying here!
