Location is perfect.
We stayed in flat No1, as there are few flats by the same owner.
There is no window in the bedroom. But there is ventilation. Bed is very comfortable.
We enjoyed a lot big living room with a little terrace. Kitchen is equipped with all necessary stuff. There is a dishwasher ( tablets provided) and washing machine, microwave and brand new refrigerator with freezer.
When we had minor issues with-old butteries in the remote control or changing bulbs- Alexey was prompt to deal with that.
The only possible issue with the flat is the noise as the doors in the flat are very thin and we heard noise from the bar in the brewery. But we didn’t hear any traffic noises which is excellent as flat is very central.
In case you’ll be unlucky to have very noisy neighbors having a party all night - you might not sleep very tight, as it happened to us.
