I stayed in in Grainnes "Michael Collins" apartment for three nights whilst visiting friends in Dublin, and the experience was very good. The apartment is roomy, very clean and the facilities, decor and furnishing all to a high standard. The location is ideal for getting into the city, being very close to bus and tram links, and there are a couple of small supermarkets within a few mins walk.
Grainne gave very useful advice about transport links and local amenities before the visit, and was checking in and out was very unfussy. Highly recommended, I would certainly stay again!
