Elena is very responsive for any queries, provides almost instant answers.
The flat is new, nicely decorated, with everything you may need.
Location is just perfect, close to everything, transport is rarely needed.
The nights in flat are really quiet although if you go outside you will immediately face roaring city's nightlife.
There could be some noise in the morning (> 9 am) during weekdays from the clothes store nearby - not that big though.
Overall I had really pleasant stay here and highly recommend :)
