Klarks place was an excellent base for my first two weeks in Madrid.
The place is quite large for a studio apartment, with clear areas for living space, kitchen and bed area. The kitchen is fully equipped and the WiFi was fast.
Klark was an excellent host, always quickly responding to messages and dealing very quickly with a minor inconvenience that happened midway through the trip. I ended up extending for a few more days in the same Airbnb and this process was seamless.
I very much enjoyed my stay, and thank Klark for being a wonderful host.
