We didn't meet Diego, He was on holiday, but we met Guillermo who was house sitting for him, he was the kindest, sweetest person that we ever met. Anyway, The location was good, close to metro and bus service, also close to supermarket. However, Our bedroom was small and was not as good as the photo make it seem, and also apartment was not as clean as we expected. We had access to the kitchen for cooking which was great, but there was no place to eat, there was no kitchen table or a chair to sit on anywhere, we had to take our food to our bedroom and eat or drink our coffee sitting on our bed.
On a better note, those were small issues, we had a great time in Madrid.
