Tom's apartment is well located and its cheaper than most of the apartments in this neighborhood. That's it for the good points.
As for the bad points : the apartment is generally extremely dirty : it appears that the carpet floor has not been vacuumed (not to mention washed) for a very long time and you fear of getting diseases when you walk barefoot on it, there are a lot of spider webs in the corners...
Special mention to under the bed: coton buds, plastic glass and other trash among the dust.
Also the sheets were dirty when we arrived, Tom provided us clean ones when we asked, saying that the cleaner should have changed them before our arrival, apparently he had also forgotten the vacuum cleaner...
In the bathroom, the sink is leaking and the shower evacuation is blocked, which means water overflows from it. So after a shower and a teeth brushing you can be sure that the bathroom is flooded and cant be used for the rest of the day.
The apartment is on ground floor, with large windows (which the cleaner has also forgotten to clean) on the street: everyone sees what you do when the curtains are not closed.
As for the furniture, there is less than the minimum : a bed, 3 chairs but no table !
Finally communication was not that good : we had to ask the day of the check in how to proceed to enter the apartment and didnt get any direction for the check out.
All in all, if you look for a cheap accomodation in the center of expensive Dublin and you are not too cleanliness-concerned this might work for you, however you'd better look for something cleaner !
