I had a great stay in Drumcondra. The house is really well connected to the public transport lines and you can expect to be in the City Centre within 20 minutes. The room itself is just like in the picture, so if you come with really bulky luggage it might not be perfect. For everyone else it's indeed a viable option. The hosts are super nice and helpful, I couldn't wish for better people :)
Overall I had a positive experience.
