I stayed for a whole month at the apartment, and I enjoyed it very much! I would definitely recommend it.
Pros: BEST communication with host Ana. Every time I had a question, she responded very quickly, and helped me out. Also, there are folders/brochures in the apartment of all the touristy things to do and see in the area. The apartment looks exactly like on the pics: modern, clean and spacious. There are some (kitchen) supplies that come in very handy with a long term stay: e.g. food containers, but also the basics for cooking (salt, pepper, olive oil). All the equipments worked well. Location: within 1-3 mins walk there are different busstops with buslines that take you all over the city.
Cons: I missed some nice, fun restaurants closeby to the apartment. The neighborhood is a bit in the outskirts of the city, so a bit quiet.
