I have to say that by reading these reviews, I see that most of the experiences have been positive. For myself, I'm afraid I have drawn my own conclusions which are anything but positive. The 'hotel' is in quite a good location. Just about ten minutes walk from Dublin's infamous O'Connell Street. The walk is quite hilly though. Speaking of climbs, as this hotel has Georgian roots, I found the construction to be of the same era - shallow steps on the staircase to accommodate those Georgian and Victorian ladies. However, this extra climb on the stairs means that the rooms (which start on the second floor) are really quite difficult to reach. There is no lift and carrying luggage does pose a problem, even for the most fit individual.
The room was terrible, resembling a kitchen with tacky chipboard constructions made into fixed drawers, cupboards and dressing tables. Oh, and a formica surface if you're lucky. There were no spare plugs or electrical sockets, so if you need to charge your mobile phone or laptop, you're in diffs! There are no tea and coffee making facilities in the room which also seems extraordinary in this day and age. However, tea/coffee can be served in the lobby on request and it is complimentary.
Turning now to the shower. It was truly awful. The shower cubicle curtain looked as if it may have been reincarnated from an old bedspread. No pressure in the shower what soever. This is a major failing of ANY hotel. A nice shower before one goes out to the town or gets up in the morning is imperative. It makes one feel good. So when I discovered that the shower was effectively 'useless' it put an immediate damper on my stay.
The only saving grace was that I stayed there for just TWO nights. The breakfast meanwhile was nothing to write home about either with stale bread and poorly cooked breakfast.
I would hate to have to stay here again, as it is positively my worst stay in a so-called hotel in Dublin. I agree with reviewers who say the staff were friendly but what's the use in complaining if you're only there for such a short time. The Dergvale is okay if you just want somewhere to lay down your head - but it'll cost ya!

The Dergvale Hotel is a lovely Georgian privately owned Hotel in a quieter part of Dublin not far from the Parnell Garden of Remembrance.
The Hotel is very comfortable indeed however there are no lifts. The breakfasts are very good.
The Hotel is situated at the top end of O Connell St. The other side of the river Liffey from the Temple Bar boozy area. It is approx 15-20 mins walk from there. So if you are going to Dublin for the beer and entertainment and night life this is possibly not the place for you.
If however you are going sightseeing and taking in the culture then this Hotel is a lovely warm friendly comfortable base for a reasonable price. The City tour bus can be accessed about 5 minutes walk. All other buses can be caught not far away either ( get a bus rover ticket to make full use of during your stay.).

Would strongly recommend a tour of Kilmainham Gaol and if its Seafood you like and you have the time. Get the 31 bus out to Howth. Its a fishing Port in Dublin Bay and the Fish at the Bloody Stream Pub is absolutely gorgeous and not too expensive.

Another Tip- food can be very expensive in Dublin, but there are some good bargains.
Try the Polska Kuchnia buffet cafe in North Earl St. All you can eat for 8 euros. The buffet is Polish and Eastern European cuisine. The variety of food on offer is so broad that it will appeal to even the most conservative palette. Its basically on the GPO side of the Liffey straight up from the Waterloo bridge across the river from the Temple Bar district. Also open from 12.00-9pm.

Small, clean and nice guesthouse North of the river located in what we immidiately called China Town.
Freindly staff, Olga is kind.

Would be nice if the receptionist had some pain killers, as I woke up in the middle of the night with a terrible headache and went to ask them for a few tablets but they do not stock that.

Only minus was that they room was very small but is was quite all right for 3 nights as it was clean and quiet. No noise at all.

A very nice family hotel, everyone was so friendly and helpful. I felt like home there and safe. The rooms were nice and clean, the breakfast was great and more than sufficient.
O'Connell Street is in walking distance and there are buses available as well. It was such a nice stay and I would like to come back!
