The difference between Helena and most others are the thoughtful touches and the affection with which she operates. Providing a kettle and snacks in the room was a lovely touch. Also I had forgotten to pack toothpaste, which she therefore provided when I asked. Her responses were very prompt and very helpful.
I was a little bit of a clumsy guest as I returned to her home late (at around midnight) and struggled to get the front door open. Luckily for me Helena was very understanding and didn't seem to take offence by the slight disturbance.
The apartment itself is very big and extremely close to the city centre; the metro station is literally only a matter of seconds away. There is a big shower and bidet in the bathroom too. The room was absolutely flawless.
