I want to thank MaCha for the great comunication and thanks for let us leave our luggage a bit earlier than the check in time., that helped us a lot. We have everything we needed. Clean and comfy beds and hot shower, and a place to prepare the breakfast.Her place is very cozy,close to everywhere, Berlin Wall is two stops by subway.Although is close to pubs, we didn´t listen anything once inside of the building.Great idea the keychain, we used it :)
