Hidde's place is located in the Quays near the Silicon Docks, less than 20 minutes walking to reach Trinity College and Temple Bar, and not far from major bus lines. Dublin itself is a fairly small city, so we had no trouble getting around.
The room itself is private, but in a shared apartment, so just know going in there might be other people around. We never met Hidde's roommates though we did hear them coming and going. Hidde wasn't around to meet us, but was super helpful in facilitating the pickup of the keys from his colleague about a 10-minute walk away and was very attentive to messages throughout that process. Thanks for the stay, Hidde.
