Nacho was extremely helpful, especially when we got lost negotiating the horrendously complicated one way system. We were welcomed by his cousin who explained things well and gave us some good tips.
The king size bed (uk) was very comfortable and the little terrace nice for a drink. The flat was just right for a few nights, near to supermarkets and bakers. We did find the neighbours a little noisy.
It was about 30 minutes interesting walk to the "monumental area" but we did find several useful buses when we needed to escape the rain!
