Good situation for sight-seeing etc. Easy to get to from the airport, with a choice of two Metro stations. Plenty of places to shop - and Lidl is only a fairly short walk away. Plenty of restaurants close by.
The facilities in the apartment are very good and pretty much everything you need is there - you might want to take an adapter if you want to use an electric razor or toothbrush charger.
All in all, a very enjoyable stay and Sven's co-host, Sandra, was very accommodating.
