The apartment is superb. In a very centric area, 10 minutes away by foot from the Cathedral, which is in the middle of the central district.
The public transport around it is very good with an underground station a few minutes away in almost any direction. There are also some very good restaurant around.
The apartment is taking out of the past, Roman put a lot of effort into replicating the looks of an apartment from the 70s yet completely comfortable for people of the 21st century. Very comfortable and spacious. I stayed there for almost a month and didn't have any problem. Roman was very helpful with some small requests we had during our stay and everything went very well. You would certainly enjoy a stay in this apartment.
