location is perfect. easy access to public transportation, museums, a large supermarket close by, restaurants, shopping, and just walking to absorb the center of berlin. spacious apt esp since we each had our own bedroom. the lobby and hallways are dingy and could use sprucing up. i suggested more soap and an upgrade on the wifi to katarina. check in and check out are as simple as can be. K responds in a very prompt fashion. we never met but connected by email several times.
