Marie's apartment is perfect for exploring Dublin. The apartment actually feels bigger than it looks in the pictures, there is certainly plenty of space in there and everything you need. A fully equipped kitchen means you can cook easily and there is a tesco local and other shops nearby. Teas, coffees, condiments and even cans and snacks are provided by the host which I think is really thoughtful, so I only needed get milk (the local telco has many milk alternatives for vegans etc) and food for myself to cook and eat, if you're hosing to not eat out all the time etc.
The BEST thing about the apartment which all the other reviews say is the location. Being in the heart of temple bar is a joy, the street is bustling from midday yet because the bedroom is at the back of the apartment it doesn't affect you getting a good night's sleep. The balcony looks out over the main temple bar strip which means even having around the apartment is fun, you're already in the thick of it.
The bed is great, lovely and comfy and the shower really nice. I stayed early jan and the apartment is lovely and warm. You save a lot of time walking across the city by being based right in the centre at Marie's apartment, and it is obviously therefore close to all transport links. It's great to be able to leave the apartment and run by the Liffey too for any runners travelling to Dublin.
The apartment is clean and nice with everything you need for a long weekend or longer really, you could easily spend a good week or so here. I won't think twice about returning to Marie's apartment when I next visit, everywhere else will feel quite secondary in comparison.
