Lovely 3 day stay at Hae-Ok's very centrally located flat. Hae-Ok very kindly met us upon our arrival, even though we arrived close to midnight. The flat was very spacious, perfect for what we needed and had stunning views of the city in both bedrooms and the living room/extra bedroom. Would have happily stayed another 3 days!
Hackescher Markt station is right outside (with lots of bars/restaurants/shops), Alexanderplatz (even more shops and the Fernsehturm) is five minutes in the other direction; so perfect location for transport. Saying that, the flat is so centrally located, right next to the Museum Island, we went almost everywhere by foot. Would very happily stay again in the future.
