The apartment's location is perfect! It is situated right next to a nice, green area in a very lively part of Stockholm. One can get to most of the main tourist spots by foot from the apartment. At the same time, the apartment is sort of hidden on a very quite street so that it is not noisy at all.
The apartment itself is very small. Especially the kitchen and the bathroom are really minuscule. This is important to keep in mind, especially since this is not exactly obvious from the pictures. Nevertheless, we could still manage to do all our cooking in the limited space available.
The communication with Elias was flawless. He was always very responsive and helpful. Also, getting to the apartment, relying on Elias's instructions, was very easy and straightforward.
Given the size of the apartment, the price at first seems to be quite high. However, this has more to do with the general price level of Stockholm than anything else. I can only recommend spending a few extra Euros/dollars, and staying at Elias' place, than saving some money and then having to commute everyday to the center.
