Location is very nice - embassy district, very nice safe and quite, at the same time very close to city center. Flat has just everything for a comfort stay, washing machine, cooking facilities, what I liked - music system in bathroom:) Art Deco is one of my favorite interior styles so I enjoyed it a lot.
Only thing - if you have lots of luggage (we had 4 suitcases with my friend) prepare to walk on steps on first floor (no elevator).
And finally - I would recommend this apartment for sure!
