Me, DH, DS 20 and DD 19, fancy a city break in summer. The last couple of years we’ve done Helsinki, Tallinn, Stockholm and Copenhagen in summer and we’ve been to Prague and Reykjavik in winter and loved them all. Don’t want anywhere too hot, thinking maybe Oslo, Berlin or Krakow as haven’t been to any of them before but wondered if anyone had any tips? Any advice gratefully received x
