Super friendly host, top spec flat, great location for public transport to get around the city. The area and accommodation is safe and quiet, with lots of great bars and restaurants in easy reach walking or public transport.
Recommend the Fez Turkish and Goldene Hahn (Italian) restaurants east to get to on the underground.
The room we stayed in had plenty of space, beautifully furnished, very trendy. We did not feel our trip was in any way affected by the works in the inner courtyard, and the flat is totally finished inside.
Theresa welcomed us into her home and showed us around on check in. Everything we need was there if we wanted drinks and snacks.
Recommend the free walking tours in Berlin, the guides are self employed and so you can contribute what you think the tour was worth at the end. Also the DDR museum and Reichstag tour was interesting too. (Book the Reichstag tour online before you go, have to pass security checks)
Public transport is easy and cheap to use with the help of google maps, 7euros a day give you unlimited travel in Berlin on underground, bus, train and trams. (January 2018)
Great trip and hope to revisit soon.
