What a lovely post!
The cafes you chose in St. petersburg are beautiful, with lots of nice textures and interesting light.
The idea of being able to take off my shoes and sit on fluffy cushions on the carpeted floor to sip my coffee or tea and read appeals to me strongly. I've always wanted to set up a part of the house to do this--and add a couple of hammocks as well--; I just hope I don't spill coffee on the carpet.
Your photos are pure aesthetic fascination, as always.
