Philipp's apartment is perfect for a city break in Vienna. The location is really good. You can get to all the main sites by metro - there are 2 metro stations (2 different lines) within a 10min walk from the apartment. There are supermarkets within a 5min walk from the apartment.
The apartment is connected (but isolated from) Philipp's home so your host is available.
Philipp provided us with a fan which helped us to sleep in the hot weather which we really appreciated! The bed is very big and comfy. It is quiet at night.
The kitchen is very small but fully equipped including a dishwasher! Cooking essentials such as seasoning and oil are available. A coffee machine is also available. The bathroom is nice and the shower pressure is good.
The parking is next to the apartment in an off-road parking lot for the apartment block. The gate is not shut at nights so this isn't secure, however Philipp advised that the location is very safe. Children play in the courtyard which made us a little nervous for our rental car but we had no problems!
I would recommend this apartment for a short stay in Vienna!
