We stayed at Ryan's apartment a couple of nights, and the experience was great!

The apartment it was as Airbn explained. The room have a confortable bed and we had our private bathroom.

It has also a big living room and a kitchen with all the stuff required.
Ryan was very kind let us picking from fridge all we wanted.

The localitation is great, just 20 minutes to O'donell street (the main street of Dublin) but if you don't want to walk, you also have a tram stop in 3 minutes from the apartment.
The neighbour is peaceful and safe.

In conclusion, If we return to Dublin some day, we contacted to Ryan again.
