We were 4 of us staying in Daniela's apartment and it was great! Check in was smooth. Daniela's father helped us check in and explained us everything in detail about the apartment. Daniela left us a cake too on our arrival which was great. Apartment was clean and had all the amenities required. There was one bedroom to accomodate 2 and a couch in the living room for 2 persons but it was spacious.
Apartment was walking distance from the famous Schonnburn Palace, but far from city centre. So, if you are going to visit the Schonnburn Palace, would recommend this apartment.
