Positive Reviews

Nice location

If you don’t want to stay in Dublin city centre, yet be within easy reach of the attractions should you feel like visiting them, you'll find the location is perfect You’ll be able to explore the Castleknock Marina area and go on long walks in the Irish countryside.

Friendly staff

Most guests agree that you’ll get a warm welcome The staff seem to be friendly and attentive to their guests needs Reviews often single out individual members of staff for specific praise, so it does appear that the team play a big role in the enjoyment of your stay.

Nice food

The food on offer, while not to everyone’s taste, is generally appreciated and well-liked The Irish breakfast, in particular, seems to be a favourite, although there are plenty of positive comments about the other meals too The fact that you can eat on the terrace is a bonus.

Negative Reviews

Noise from nearby trains

The hotel is upfront about it being near a railway and pre-warn guests that the noise and vibrations may be an issue Although some guests specifically remark that it didn't bother them, plenty were disturbed by the noise, so it’s something to be aware of if you're a light sleeper.

Wi-Fi isn’t great

It isn't uncommon to hear that guests would prefer Wi-Fi to be accessible from the guest rooms, particularly as they are described as executive rooms Furthermore, guests who used the Wi-Fi is the public area often comment that they had a poor connection.

Some rooms have a peculiar smell

One comment that crops up quite a lot is that the rooms have a funny smell when you first arrive A handful of guests compared it to the smell of sewage, although most agreed that it tapered off when the windows were opened.
