Accommodation
June is a high season in St Petersburg, so the hotels may be very busy. It is a very good idea to book the hotel in advance.
This is the map of St. Petersburg where you may find HSE University. If you want to live in historical architecture with nice walking opportunities to main attractions, we recommend you to find accommodation in the pink area. There is a plenty of hotels and appartments available for reservations now through Booking.com or AirBnB (these links show the search results for conference dates). The price of taxi service from pink area to HSE building is 3-5 euros.
