Tilman's apartment is well equipped, spacious and comfortable in a very convenient location. Just 10-15 mins on tram from Berlin Central Station. As two women in our seventies, my sister-in-law and I found the stairs to the fourth floor a bit of a challenge but Tilman very graciously helped with our luggage both on arrival and departure. However, It was definitely worth the climb and we did get use to it, especially coming up and down without luggage; it very private and quiet. It was pleasant to have breakfast on the balcony which is surrounded by tall trees and overlooks the gardens below. Tilman was available to answer queries by phone/text, which was very useful. One small inconvenience was the fact that wifi connection was switched off overnight and we were not aware of this till I enquired in the morning. Overall it was great value for money and, in spite of the stairs, I would definitely want to stay there again.
