Staying at Claras place was great! She is really lovely and gave us many tips for our stay in Madrid. Her flat is close to Atocha station which makes it easy to move anywhere by bus, metro or trains but you can also walk to the city center in about 20 minutes. The place is really clean, spacious and beautiful (we loved the details and the interior!). We definetly reccomend this place and would come back any time!
