Both my girlfriend and I stayed with Natalia and it was extremely enjoyable!
I honestly have no complaints. Natalia was very friendly and communicative, helping to ensure we got to the place easily and gave us a initial tour of the premises to familiarise ourselves.
The room was clean, so were the rest of the accessible place ( bathroom, hallway, etc ) and the neighbourhood was a nice contrast to the city, quite and calm. However, it is very well connected, with a tram station essentially in front of the block. It never took us more then 15-20 minutes to get in the centre.
I highly recommend Natalia as a host!
