Cristina's place has everything you could want for a stay in Vienna, and its location literally seconds from a U-Bahn station means you are never far from the many wonderful sights the city has to offer.
Cristina herself was an excellent and very helpful host - always quick to respond to any query, large or small, which means you are just a short message away from pointers or recommendations, should you need them.
The apartment itself is exactly as advertised - clean, modern and airy.
I will certainly consider staying at Cristina's again next time I visit!
