Claudia's flat is just perfect for a long or short stay in Vienna, whether for work or vacation (for me it was both, visiting Vienna for a two-day congress and then a three-day Vienna experience). The flat comes with all you need (even comfy sleepers and handy pocket umbrellas!), is full of light, absolutely quiet (it features double-glazed windows), and super-clean. Even though it was a bank-holiday time for Vienna, and most people were out of town, the self check-in and check-out ran just smoothly thanks to Claudia's detailed infos. The area is not "central" but an easy 15-20 minute walk takes you to St. Stephen's through the beautiful Praterstrasse and inner Vienna streets. And you can easily and quicky reach the area thanks to efficient Vienna's transport system (it would take me just 20 mins to get by underground and tram/bus to the premises where the congress was in the other side of the town). Still, I do advise to use Praterstern train station only to get from and to the airport (the trip isa direct one, with no changes, using S7 - don't waste your money on the fast train and don't forget to buy the ticket integration, if you wish to buy a 3 or 7-day ticket... and that's my advice, it's anyway worth it) and especially at evenings - when Praterstern is a kind of drunkards' and bums' cove - to use the other two underground stops of Nestroyplatz (red line) and Taborstrasse (purple line), just as close to the flat. Praterstrasse is full of cafes, typical "konditorei", supermarkets. Do try the bakery just out of the main entrance of the building, not so fashionable, but really good. To sum up, Claudia's place is a really good deal for price and quality. I would definitely come back, if I had to stay in Vienna again.
