The apartment's location is really good: 500m, 6 min. walk to Volkstheater subway station , 8 - 10 min. walk to MuseumsQuartier. That was really convenient. Close to all major attractions in Vienna. The issue we had was poor WiFi coverage and speed. When we arrived, we could not connect to WiFi at all: I called Bertrand to find out that I had to plug the WiFi device in, then push both buttons to reset it. I did that, and we were able to connect. Not a big deal, I thought, though I didn't understand why it was unplugged to start with. The WiFi speed was slow: 10 - 14 MBs, and that was a real concern since we had to do a proctored online COVID test in the last 24 hours - to fly back to US - and that required video connection. The next morning the WiFi connection was lost, and I had to restart the WiFi device again. The other issue was the poor coverage: no reliable connection in 2nd floor bedroom, and no connection at all in smaller 2nd floor kids bedroom with bunk bed. That was a problem since our daughter needed to study online to get ready for the test, and she had to go downstairs to get WiFi connection there in the living room. Not an ideal situation. Bertrand suggested using the stick form his computer, but the app there was really old and could not be used with the latest Mac laptops. Couple days later we could not connect to WiFi at all: the message was to make a credit card payment to restore the service. We called Bertrand, and he reactivated the account the next day. We were glad it didn't happen during our last day when we had to do online COVID testing. To summarize, it's a nice centrally located flat, good for people that can tolerate unreliable WiFi with poor coverage.
