I stayed with Jimena for a VERY brief stay as I had an overnight layover in Madrid and wanted a bed to sleep in instead of trying to sleep at the airport! She went beyond my expectations with her flexibility and hospitality including pick up at the airport (for an added fee) after midnight and returning me for 6:00 only hours later. It was a very basic room but very clean and everything I needed for my short stay. She was very warm and welcoming. The only evidence of a dog in the house was a bit of barking when I first arrived - there was no smell or dog hair anywhere to be seen! One thing to note is that the apartment is on the 4th floor with no elevator...I was thankful my bag was checked through to my final destination for that reason! I would be happy to return if I ever had a layover in Madrid again!
