Sylvia is a very nice host, told us everything we wanted to know. Place was clean and had everything we needed. The only not so great thing for our first stay in Berlin was that it is a little bit far from the city centre. with bus and uban it took us around 45min depending where exactly we wanted to go that day, its a big city. But with your organisation and google maps you can still have a great time in Berlin and also see the suburbs ;)
