Lena's house is very clean and the room has a lot of space. This is, in part, due to the lift bed. We thought it was a really cool bed, though it wouldn't be suitable for people with poor mobility.
Lena's place is quite far from the city centre, but the transport (particularly the underground) is amazing. We had no trouble at all getting to the major landmarks.
Lena is very nice and friendly, her home is warm and cosy, and she was very accepting of our late check-in time. She was equally flexible with checking out. In addition to this, Lena messaged us some very comprehensive instructions for finding her home, after I told her what station we would be arriving at; she is clearly very accustomed to having people stay!
The one thing I will say, is that essentially and basic amenities were listed on the room page, but there were no towels. (It might state that somewhere, but we didn't see it.) Luckily, we already had our own in our bags. :-)
