Everything went well! Check in went smoothly, the communication too. The location was great, right next to the Istiklal street and very close to airport bus.
It can be a little bit loud during the night at weekends, and there is no elevator - means you have to carry your luggage to the 4th floor (stairs are very narrow).
We got additional towels as requested too.
All in all, great accomodation for the price :)
