Marvin is a super host and his place is one of the best we stayed in. The cleaningness is on absolute point, the house is very pretty and they thought of all details. You even have hand cream on each bedside table <3! Also, they even borrowed us an umbrella for the entire stay :D.
The location is very good even though is outside Dublin - the bus that takes you directly to the citycenter is 15 mins away by foot.
The light breakfast Marvin offers comes very handy (snacks, cheese, butter, apples, yoghurt etc.) and you get all privacy you need.
I can’t think of any reason you wouldn’t choose Marvin. I totally reccommend!
