Clontarf Castle Hotel may not be right in the heart of Dublin but it is not hard to get around. Taxi service is always available with a simple request at the front desk. The ride isn’t far and normally runs around 10 EUR. If you don’t want to spend for the cab you can always make the walk which is 5 kilometers to the Temple Bar area. Another option and possibly the best if you want to see a lot is the hop on hop off bus. The rate is 18 EUR per adult for a two day pass and two children under 14 ride free with an adult ticket. There is a stop right outside the hotel so you can just hop on in the morning and get on or off at any stop in the city you want! Read here for more info.
