Not at all fancy, but pretty good value for money at this below-ground flat. The TV, the AC, the fridge and the shower were functioning just fine, and that's more than some hotels I've stayed at in this area!
That being said, it's not a place you'd want to actually spend time in. It's very small and if you're more than 190cm tall, you'll knock your head in the shower "roof". Also, if you got room to spare in your suitcase, I advise you to bring your own towel, as the ones provided we're tiny and hardly absorbent.
But if you, like we did, only need a place to crash for the night and to get ready for a busy London day the next morning, it does the trick. Communication with the host was smooth, and the key delivery was delightfully hassle-free.
Leinster terrace bus stop is right around the corner, and the schedule to central areas is pretty good. Also, you got a couple of decent pubs/restaurants/shops right on the street, for refreshments and meals if you don't feel like going far.
