Location: The apartment is in a good location, though on a busy street and it feels a bit bare/un-cared-for coming in the main door. The Spar grocery store just steps away is a wonderful thing, and there are many museums within 5-10 minutes walk. The Metro station for Museumquartier is very close (though it is necessary to transfer to another line for most tourist sites). Large elevator is very handy for luggage. Good gelato place just around corner. Apartment feels very secure and safe.
Apartment: The apartment includes what is shown in the pictures. Everything is fine for the price of this listing. It has many dishes/silverware and pots/pans, and has a few cooking items (salt & pepper, tea). Kitchen pans needed re-cleaning before use. A few things could use some touchup (wall paint, furniture cleaning, towel bar), but the hardwood floors, surfaces and bathrooms were very clean. Only two bath towels provided per person for a 4 day stay (no hand towels, washcloths, bath mat, etc). No storage space for bathroom toiletries (the limited space was taken up by cleaning products). Lighting was very dim in main rooms at night (kind of gloomy), though large windows made it bright during the day. For english speakers, only two english TV channels (both news, and hard to find in the guide). Stall shower had nice water temperature setting control.
Communication: it was fine. Received very short responses within a day. Person who met us at the apartment was the cleaner and very nice, but was not someone that we could contact.
