I really enjoyed my night at Angelika and Jorge's place. I haven't had the chance to meet them, but their friend Nico was great and very helpful.
The apartment is really big, the kitchen is well equipped and there are two bathrooms. It was very clean and quite.
The apartment in the heart of Madrid and close to everything you need (shops, restaurants, etc) and a few minutes from some cool places to visit.
I highly recommend and would love to stay again.
