Excellent place, very clean and comfortable. Is very much like what's showed in the pictures. The kitchen is well equipped, but you will need to buy all seasonings to make food.
We stayed for a long time (4 weeks) and the apartment was cleaned once a week during that time, with clean sheets and towels provided, which was great.
The neighborhood is really good, with many restaurants and shops, and is close to the metro. There is a supermarket right in front of the building that opens everyday until 23h, which is not usual in the city but was really useful for us.
As for the communication with the host, I followed the instructions that were given with the check-in instructions and had no problem. The responses were very fast and helpful.
