We have stayed at this amazing place and it was just amazing.
The penthouse is luxuous, very clean and very well located. Most importantly, Ali and Alp have been there for questions and the welcoming was just amazing ! You feel like being at the hotel with someone taking care of you.
They have a great organization, the penthouse was more than what we expected and the service was beyond our expectations.
We would highly recommend this place to anyone and would certainly return when going back to Vienna !!!!
