The apartment is very nice and perfectly equipped. Since I was traveling with a small baby I noticed that the floor was not super clean, but the rest was fine.
The location is great cos very close to the city centre and to the Atocha station.
The host has been very kind in letting us in before the agreed time. However, we had some issues with communication later on.
The first night of our staying she asked to enter the apartment the following day for a debugging. I gave my availability in principle, but when I asked for more information about the type of products they would use, she disappeared. I discovered two days later that she gave the access to the technicians it without letting us know. I also messaged her about the wifi connection which didn't work and she also ignored my message about it.
