Igor is a friendly guy that speaks good English, a rarity in Russia :-) Communicating with him was therefore easy, and he responds fast. He gave a few tips on Nizhny upon arrival and we could contact him if we needed additional information.
The apartment building itself is a bit dodgy, from the 50s, if you're not from Russia you will probably have to get used to it a bit. The apartment of Igor however was clean, the bed was good, there's fast Wi-Fi, a couch, enough kitchen utensils for some basic cooking and a hot shower.
I would recommend this apartment for its convenience, price, friendly owner and for being close to the main street of Nizhny!
