Peter was definitely very nice and friendly.
Most importantly: this location is absolutely perfect to catch a train into town while leaving your vehicle parked on premises and avoiding the EXTREMELY costly parking in the heart of Dublin! The train station is literally across the street and makes getting just about anywhere in town an easy walk.
The place was spotless and the washer and dryer is definitely a huge bonus if you're trying to pack light.
The only downsides are that it is up a couple of flights of stairs if that is an issue (and it wasn't for us), it is a shared building so being quiet and courteous is a must (also not an issue for us), and lastly the trade off for being so close to the train is also being so close to the train. Honestly the intermittent noise was not an issue in the least for us, and it was fully disclosed in the listing to boot. The train doesn't run all night so even if you're a light sleeper a good night's sleep won't be an issue.
Highly recommended!
