Lela's apartment was very easy to find and she gave me very clear instructions. Unfortunately I did not get to meet her as she was busy, but she told me the entrance code, code for the keysafe and everything was very easy. The apartment was very clean and spacious with 2 bedrooms and a sofa bed. However, the toilet was a little bit too small, but we were barely at home anyway. The apartment is very close to the metro and it is only about 10-15 mins to the main spots of vienna.
