We stayed at Elsa's place so that we could be close to the airport to catch an early flight. It so happened that there was a taxi strike in Madrid while we were there and Uber was also not working. Elsa's apartment was close enough for us to walk to the airport (just over 30 minutes to Terminal 2). Elsa was kind enough to stay awake until 3 am to serve us breakfast before we headed to the airport for our 6 am flight. would definitely recommend her place! She is a very thoughtful and caring host!
