In my small Soviet time flat I can offer a couch for two- three persons in my living room.
My offer is for persons who is looking for a space where to stay for a night or few nights and are not very demanding.
It is not a hostel, and it is not a separate appartment, I offer a space in my living room.
I have no pets and I am a non-smoker.
If it is OK for you, you are welcome!
