In short, this apartment is really great. I would recommend it to everyone and I will come back in the future for sure.
The communication with the host is fast, friendly and very helpful. Check-in was easy and also possible at later hours.
The location is superb. Everything is reachable by foot. There is a carrefour 2 minutes away, a metro station 4 minutes away and restaurants everywhere around the apartment.
The kitchen has everything you need to cook for yourself, especially for breakfast.
One thing that should be mentioned and that should be considered is that this apartment is in an area which is very lively during the evening hours. There are lots of bars and restaurants around and especially on the weekend they can play loud music until late in the night, like 1, 2 or 3 am and there are lots of people on the street. If you are a light sleeper you may want to think twice about staying here.
I personally liked it, because it was lively and not as dead and silent as other places in the city.
One more small advice: Listen very carefully to how the alarm system works. I got a heart attack when I set off the alarm by accident. :D
