WiFi does not work consistently, so get a data plan. There is no tv, so streaming will be the only method and the WiFi signal is extremely poor, sometimes not connecting at all.
Also, be prepared to do a lot of walking on hills. The house is not convenient to anything nearby without a car, so consider renting a car. It is a 20 minute walk to and from town. Due to the lack of WiFi it is difficult to coordinate taxis or public transportation.
The space has a lot of potential, but it not very functional in design or decor. Decor is also not stylish at all. If you don’t mind camping, you will be ok with these accommodations.
Bring snacks, plan to have your own breakfast. Very little is provided despite “breakfast” being included. The kitchenette is not very functional.
It was lovely staying in Howth versus the city. This particular place just was inconvenient and not very nice.
