I know Nina has many good reviews, but it is always important reinforce how nice her place is. Clean, very well organized, warm (including hot air conditioner...and it was -10C outside when I was there), very short walking distance to city center, close to everything you may need (subway, train to the airport, shopping, food stores, wonderful restaurants, night live and etc).
Besides all this, Nina is a very attentive and lovely person always available to give all support we need. Thanks Nina. I'd love to be back one day. Danke schön...!!!
