There are several hotels on walking distance:

Hotel Nieuw Minerva

Hotel Nieuw Minerva is situated in the city centre on one of Leiden's many canals. It is located on walking distance of Leiden Central Station and the Nieuwe Energy (Meeting location). Nieuw Minerva is small family ran hotel in a friendly, Old Dutch style with a homely and interesting atmosphere.

Directions from train station Leiden:

If you are coming by train, take the main exit of the train station. You have to follow the road, this is Stationsweg and than called Steenstraat. At the end of Steenstraat cross the bridge and turn right. The second street on the left is Boommarkt.

From Hotel Minerva to de Nieuwe Energie: leave the hotel and cross the bridge in front of the hotel. Continue onwards into a small street until you hit the main shopping drag (Haarlemerstraat), a pedestrian only zone). Turn right and continue for about 100 meters until you come on a small square with a church on the left hand side. Turn left and walk down the 'Mare'. Keep going; cross a bridge; keep going; cross a wide road and keep going. But do not cross the next bridge (with a large HEEN sign and something which looks like a silo); instead turn right. The Nieuwe Energie is at the end of this street (3rde binnenvestgracht).

Hotel Golden Tulip and Tulip Inn

Is located right next to the train station Leiden.. It is a typical corporate/US style hotel. See the venue instructions for how to get there.

Other hotels and will also suggest the IBIS (also near the station) and Rembrandt Hotel (bit run down - but very easy walk).

Note that the Marien Poel hotel, Holiday Inn and Bastion Hotel are significantly further afield - and will require a taxi.
