Juan Carlos' places is a treasure that I stumbled upon !
First, the apartment is top tier quality and every small bit is really well explained.
Second, the host Juan Carlos is the best host I met till date during all my travels. He explains everything you need for a wonderful stay with precise details and gives you tips about tourist attractions in Madrid and ways to get around the city.
Furthermore, the apartment had all the amenities I needed for my stay and the room was picturesque. And is a short bus ride from the Airport.
If you are reading my review don't look further this is the place you want.
Looking forward to visiting Madrid again and the best host in the City.
