Stay away.
The flat is nice and in a great position, perfectly connected by tram and metro. The area is extremely lively, nevertheless the noise is not a problem by night thanks to insulating glass.
Unfortunately, our experience with the host was very negative. The boiler hasn’t been working for the whole lenght of our stay and the water was freezing – as a result, we couldn’t have just a single shower in four days. Plus, the communication with Abu was slow and intermittent: not only he wasn’t able to solve the problem but he played for time and took hours to answer our requests for help: he also promised he would send us the technician to fix the problem before we left but he never came and we wasted our last afternoon in the city waiting in vain for him. What’s even worse is that he offered us a ridicolous refund for this huge inconvenience, and that’s even more offensive than the malfunction itself.
For these reasons, even though the flat is nice and well located, we absolutely do not recommend this accomodation. Honesty and helpfullness should be essential requirements of any host.
