The apartment is clean and comfortable, and appeared to be newly renovated. It is very conveniently situated, with the museum island and many of the main tourist attractions within walking distance - that is for those who like walking. If walking is not your thing, the public transport connections are very convenient, with an u-bahn station (Heinrich Heine Str) in the same block, and an s-bahn station (Jannowitz Brucke) just a couple of blocks to the north. The size is perfect for a couple, and everything is provided for a self-catering holiday. According to the description internet was still on the way, so we didn't expect any wi-fi in the apartment, but by the time of our visit, the wi-fi was fully functional, which was a great help with planning our daily sight-seeing activities. Martin is also a very gracious and accommodating host. All in all, we can highly recommend the apartment and Martin as host and would definitely contact him again on our next visit to Berlin! Many thanks again!
