Host is friendly, check-in and out was without any issues. Room for guest has a large comfortable bed and pillows and it was formerly accommodated by host's daughter - decorated, large library and many handbags :) I enjoyed my stay at Lucie's place. Only downsides for some people might be that, it is in the top floor and there is no elevator and that host is a smoker and there is faint cigarette smell in the apartment (guest room does not smell).
Person that rents the room is listed on Airbnb as Lucie with a girl's picture. However Natasha & her boyfriend live at the apartment. Natasha said the owner is Lucien and a guy. Very misleading. Lucie or Lucien did not assume any responsibility with any information for check-in. He/she directed to Natasha who was not very responsive. I had to wait under the rain for some other at the building to open the door. I was not informed of which bell to ring and how to enter the apartment, which floor etc. Person living at the apartment (Natasha & her boyfriend) had a dog. This was not listed and maybe a problem for some people. Big room with plenty of light and a big bed. Apartment is at 5th floor, so many stairs to climb. Cleanliness is very average. Natasha however was very kind and tried to help with what she can. Invited me to her work (art gallery), provided information for my trip back, etc.
My Girlfriend and me visited Prague and stayed in this pretty gigantic room. Bed was comfortable and the Hosts really nice and polite (they even made a spontaneous Late-Night Dinner for us), so we highly recommend to stay there if possible. But we also had a bit of trouble with the Check in (Czeck in, haha) because the hosts were at work and we had to wait for an hour outside. Nevertheless, nice and chill with art exhibition right around the Corner.
