Gerry was welcoming and gave us good detailed local tips of places to visit when we arrived.
We had high expectations after reading other reviews; however we experienced the accommodation as being adequate - toilet paper and bedding was provided but we needed to purchase our own hand soap and only one pillow was available per person. Some extra touches would be nice but this is reflected in the price of the stay.
If you're arriving at the airport, then we would recommend getting a Hop On, Hop Off bus ticket which takes you around the city, giving you the option to visit all the main tourist sites (such as Guiness Storehouse, various museums, parks etc). This can also include an airlink bus from the airport to the city centre (which takes about 30 mins). We really recommend the Ghost Bus Tour!!!
The city centre (e.g. Temple Bar) is a 30 minute walk away from Gerry's place. We wished we had more time to explore Rathmines which was only a couple minutes walk down the road - Blackbird and Stella Cocktail Club (you'll need to book a table here) are great places to drink.
If you're after a no frills stay that is all about value for money, then Gerry's is the one for you.
