Overall, I would highly recommend this apartment. Here are the "pros":
* It had four good-sized bedrooms and two bathrooms, a nice kitchen , a big table with lots of seats, a TV/sitting area, and beautiful views!
* The beds were comfortable with good mattresses and nice linens.
* There is a washer but no dryer. However, there is a closet with a drying rack that was very warm. Our clothes dried super fast overnight.
* The biggest plus of this apartment is the location, which is at the end of the "rainbow street" surrounded by tons of restaurants, shops, bars, and markets. It was within easy walking distance of all the major sites, as well as Bus Stop #3, which is on a pretty major street (can't remember the street name but the Hard Rock Cafe is on it). We took several tours that picked us up at that bus stop. There's also a taxi stand across from the Hard Rock.
And here are a few things, not so much "cons", but that I think would be helpful to know:
* There is no elevator so you need to be prepared to take three flights of stairs up to the apartment.
* No cars are allowed on the street where the apartment is; if you're being dropped off, it has to be on a nearby street. It is still very close, but just something to be aware of.
* It was a little hard to take a shower in the smaller bathroom as the shower is in the corner and there is no "berm" so water seeped over the floor.
We very much enjoyed our stay and loved Iceland so much! We plan to go back and would rent this apartment again!
