People reading this, this should be a long bad review but I prefer to go to the point so you can pick another place to enjoy the beautiful Dublin.
1) Jonathan's place is a Hotel, it isn't an apartment of house.
2) The Hotel phone number in Airbnb is not the correct phone.
3) Address and coordinates are totally wrong (read previous reviews)
4) Jonathan does not reply anything you send over airbnb platform (it has been a week and still this person has not replied to me)
5) Airbnb will only send a warning to this place, so if something goes wrong they will only receive a warning and you will have to swallow your frustration.
*Solutions*
if besides my recent warning and warning before me, you booked this place, and now you are in trouble, read below:
1) Do not use the directions provide by this site, if you google "1 Garter Ln" you will end it up in an old tiny house that clearly is not a hotel. it happened to us with the aggravating it was midnight and cold. the coordinates also will send you to that tiny house. the information is deceiving and still not sure why, because airbnb allow hotels to publish in their website.
a) to get there, you need to get inside of the hotel call "CityWest" it has a huge lighted entrance and I am sure you passed by looking for 1 Garter Ln, we did.
b) follow the long path you can see in google maps, pass the roundabout and keep walking to the next roundabout, turn left and keep walking until the end of that path, and you will find the Hotel in question. it is named CityArk Aparthotel but locals knows this place by the name of a restaurant inside (not sure if provide food) "lemongrass", so if you need a taxi, tell the to pick you up at lemongrass, easier than explain how to get to this aparthotel.
c) if you prefer to put coordinates, the correct one are these (53.28597011436749, -6.450130690667267 ) I took it by myself when waiting at the lobby. do not use the coordinates from airbnb site, they are not right.
2) I could not get any good phone number to call. Also Jonathan is not present on site.
3) Red line from Dublin is not running overnight, so keep in mind this aparthotel is 45min away form Dublin and by 11.30pm you should be boarding the red line to Saggart.
4) from Saggart station to CityArk Aparthotel is 15 min walk.
5) Room was clean, neat and shower has good pressure.
6) Fun fact, the sink in the bathroom has two separated faucets, one for hot water and one for cold water, so there is not way to mix them and get warm water. you will burn or freeze. to wash my teeth I mixed the hot and cold water in a glass and use it form there.
7) warning: two electrical outlets. also bring an universal adapter to charge everything as we did.
8) suggestion: pick another place to avoid all the above
