Maria far exceeded our expectations on this trip. Upon our arrival she generously gave her time to show us around the place (which was nicely updated). She also has a well-designed guide for guests containing listings of local restaurants, attractions and other useful information.
Often, however, it's the extra touches that matter. Her place had fresh fruit, bottled water and delicious chocolates, all of which were greatly appreciated after a long day of travel.
I highly recommend Maria's location if you're interested in visiting the lovely city of Vienna.
