I highly recommend staying with Pearl. Although the place is quite small, this is reflected in the value, taking into account the fantastic location. What really made this such a good experience and such great value, though, was Pearl herself. Very nice person, easy to chat to. Full of useful info and tips. Very generous. She offered me a full Irish breakfast every morning and even left dinner in the microwave for me one evening (spaghetti bolognese, in case you were wondering - yum). Lots of fruit, coffee, tea, etc. Check-in was easy, and all the info about the place was very accurate. Camden Street nearby is a very nice spot, but lots of even more central places are walkable. I'll stay with Pearl again if I need another spot near the city centre
