Participants will be staying at the hotel close to Vilnius center. A large-area old city (Senamiestis) with lots of venues to explore is near by. A pdf version of the Vilnius center map for tourists is here.
The exact hotel is still being considered. It takes about 30 mins to travel by public transport from the city center to the venue (stop at "Nemenčinės plentas" or "Saulėtekis"). Use a website-based trip planner or an app Trafi (which also allows to purchase tickets).
