We can recommend the stay in Irinas apartment if you keep in mind some things (and if they dont bother you).
First off all the communication upfront was perfect. We got all the information for the apartment and the key box well in advance. The numbering system for the houses was a bit confusing for us as we first arrived at house # 18 (instead of 119). When we called Irina she was very helpful and let us to the right house. She also helped us when we were struggling with the right door to find.
Further the apartment was super clean and we had everything we needed.
However we were a bit shocked by the neighboorhood and the entrance of the house. It is a very old building and the hallway was quite dirty (cat food over the floor, papers flying around, graffity on the walls). Further it smalled like smoke in the whole hallway.
Although the neighboorhood did not make a good first impression we did not feel unsafe at any moment.
Good thing is that there is a small supermarkt (5min walk) and the bus stop / tram is also just 5min walk away.
As stated in the beginning we can recommend the apartment if you feel okay with above small "negative" aspects.
