Peter's apartment is as central as it can get in Vienna. Apartment is located in one of the main squares from where the first big dynasty in Austria ruled. it is well lit, had enough space for a family of 4. large bedroom is particularly quite spacious a s the kitchen is very usable.
we only has two challenges (which is why I have rated it 3 stars and not 5 stars):
1. it was very hot in Vienna. there was one portable fan, which was not sufficient for 4 people. we asked for another, but that was not possible. It was very difficult to sleep without a fan.
2. during the stay, one of the side lamps fell from the sofa and the bulb inside it broke. I brought it to Peter's attention, and offered to leave money for replacement. he told me that it will cost 30-40 Euros. it sounded a bit too much. I went to the supermarket next door and bought one for 3 Euros and replaced it. not sure if this was a communication issue, but it did not leave a good taste.
