 I booked a double room and requested a quiet room but the first room that we were given was a twin room So we asked for a room change and were given a double room however this room was a quite noisy as it was in front of the elevators and also because there was a group of guests nearby who were noisy So we again asked for a room change and finally settled into a quiet double room The staff members were very nice but it d have been better if my requests were actually met from the beginning Nonetheless I would highly recommend this hotel 
 The location is great for not only for some who has something to do with the UN but also for regular travellers because the hotel is right next to the bus stop where airport bus arrives and is also across the road from U1 subway line The main tourist attractions e g Stephansplatz Karlsplatz etc are only 10 15 minutes by subway Breakfast was also really good
