My stay at this ground-floor apartment was perfect for my needs. I had to visit Queen's University, and therefore the location was ideal. All the rooms were well cleaned, and all appliances were in good working condition.
There are two beds, one of which is clearly intended for one person, and another bed which can fit two persons. But if one of the partners has a habit of moving too much during their sleep, the bed is not large enough to prevent the other person from getting their sleep disrupted. Since I came alone, it was not a problem at all, but if you are intending to stay as a couple, you may want to take that factor into consideration.
Most rooms have a USB charging plug in the wall, which heavy phone users will surely appreciate, but you should have a 2-3m charging cable to make the most of it. The same goes for laptops, as you will need a 2.5-3m charging cable to work in the dining room table without moving the table itself.
It is a very quiet neighborhood and excellent for concentrating on your work. This is NOT a place for partying, even if nearby there is a street with pubs which may lead to ocasional noisy teenagers passing by on Friday night. You will easily find small markets and fast food stores nearby. Overall, I absolutely recommend it, if you need to visit the city center frequently.
