Thanks! I need a Sim card and 2 SD micro cards with a lot of memory... Perhaps I'll get a real camera instead of photographing with my mobile phone. I am staying at a hotel called Zamkoviy.
I ended up staying here longer than I had expected because all affordable hotel rooms in Minsk are booked, due to 9 May. If I had known I'd be here for so long, I would have rented a flat!
