Unfortunately we did not meet Emmanuel himself. His Housemate welcomed us very warm though and showed us the entire house. She was very nice and we had some interesting converations with her. She was also very helpful and offered us several times to contact her in case we would need any help. She recommended us many pubs, restaurants and things to do.
The location of the apartment is great. You can explore all the nice areas of Dublin within walking distance (10 min. walk to Temple Bar, Jameson Distillery, 15 min. walk to the Guinness storehouse, Trinity college etc.)
Also the Aiport is easy to reach from there. The room was rather small but enough for my two nights of staying at Emmanuels.
It was my first AirBnB experience and it was a great one.
The house does need some cleaning (floors, kitchen, bathroom) though.
