Fantastic. If you are looking for a quiet place to stay that's convenient to all of Dublin, this is your place. All of the amenities are as described. I appreciated the cleanliness and secure, well-lit entry. The neighborhood is beautiful, rather upscale, and safe. Only about a 10-15 minute walk into St. Stephen's Green and Grafton Street shopping, which then shortly connects to Temple Bar, Trinity College, and more attractions in northern center city. I took a leisurely walk of the whole center city my first afternoon and still finished within 2 hours. The bus stop is a five minute walk from the bedsit, and drivers are friendly enough to help out someone new to the city. I used the bus often. Taxis are readily available and easy to hail on main roads (pay cash). If you are accustomed to Uber in the US, download Hailo (the Irish app--despite bad ratings on the App Store, it works perfectly well and there are lots of drivers. Ubers are not plentiful and will take 20 minutes to reach you.)
Aside from the general tourist activities, I would also recommend checking out Ranelagh's main strip, a short walk in the other direction. It is a nice neighborhood and, I learned, a popular living spot for students and young people. The National Concert Hall is also close by, and offers diverse and affordable programming. If you have time, take a day trip to the countryside--I did Glendalough and Kilkenny by bus--for a view of scenic green Ireland.
Eamon was a great host, helping me out with an early morning arrival, answering promptly to any communication, and even providing milk for my tea. The linens are clean and bed comfortable. The bathroom is new and clean. It is clear that TLC is put into caring for these rooms, and it makes for a really lovely stay. Overall, I felt safe, well-rested, well-cared for, and as equipped to explore the city as one would feel at home. Do not hesitate to book this lovely bedsit.
