I had a great stay at Nikos place for two months. The apartment is very close to the metro, with a direct line in to the city. The area is calm but nicely located with a grocery store right across the street and several within 5-10 min walk, as well as pharmacy and everything else needed. Very close to WU for students and a great location. There is also a very nice outdoor area tied to the apartment that would be very enjoyable during times when the weather is good. Great to have a cup of coffee in the morning or dinner outdoors with friends.
The apartment is very clean, good wifi and overall very nicely decorated with great lighting and clean and spacious shower and bathroom. The kitchen is well equipped and a lot of storage area for clothing and other things.
Niko is very responsive and great with all types of communication and problems. I had one small issue at the beginning that was fixed immediately, and communication time is super quick.
Overall I can highly recommend this apartment. Good value for the level of decoration, cleanliness and overall experience. Will stay here again when I come to Vienna the next time!
