Tim was great with communication prior to arriving in Dublin. Tim also informed us that we would not be there during our stay but his brother would be there to let us in.
Getting to the house was easy as there is a very good bus service to the AirBnB. Tim's brother gave us a brief tour of the house and our room (the larger of the two bedrooms on the second floor). We also learned that he would be staying in the house (on the second floor) for the next few days and that we would be sharing the AirBnB with another couple who lived upstairs and shared the bathroom with us.
We had clean bedding and one towel per person. The bathroom was also clean but is aging (rust, mold?). The lock on the bathroom is broken, so we communicated with the other couple to avoid "surprises".
We did not see Tim's brother again, but we had the opportunity to let him know we would be leaving the morning of our third day of stay. Overall, our stay was fine.
