We had a wonderful stay in Madrid…so first the pros and then the cons:

The apartment is located in Malasana, which is a hip place…lots of bars, restaurants and entertainment…you are very quick in the city center…everything is close…metro, taxi, bus station…

The apartment was very clean upon arrival, the Wi-Fi was working, the bed lining was new and clean.
The bathroom facilities were clean, so we felt directly totally comfortable…

Nico the host was answering our emails directly, and although we arrived late at 11 pm in Madrid he organized his sister to hand out the keys to us…

Some negative aspects were noticeable:
The sister just handed the keys to us, not even mentioning in which building the apartment is located, not even introducing the place to us.

Although we had booked for 3 people, the third bed, which was a couch, was not prepared for sleeping…so we had to search for bed lining and duvets…the lining was already in the inside of the couch, so probably not new nor clean…the lower surface of the couch, facing the floor was totally dirty, and needs a cleanup!

The last thing is that the apartment is really really small…especially the bathroom and the shower cabin are tiny…everything looks much bigger in the pictures of the advertisement…

I would book the apartment definetly again, due to the perfect location and the all over clean status, but probably for two and not for three people…
