Lucie's apartment has an amazing location, it was very clean and tidy and I enjoyed the design touches put in the flat. It is a unique atmosphere and the stay at the apartment itself makes it an amazing experience as part of Your Berlin trip. I definitely recommend this flat as a place to stay.
On the con side - I would have wished for a better communication from the host side. They didn't respond on time, or on some issues never. At first there was a problem with wifi, that was fixed in a day's time. But the TV didn't work and I never got the answer, if there is a problem or it doesn't have to work.. Luckily, TV was not the reason of my choice, but I would have a liked a bit more personal attitude to me as their guest.
Otherwise it really is a gem.
