I stayed the night at Alejandra's place in between flights at the Barajas airport. It is located a quick 15 minutes from the airport using ride sharing, so it was perfect for me. Unfortunately my flight was changed and I arrived rather late at the house, but Alejandra was so accommodating and we stayed up talking for another hour and a half, despite the late hour. She is a very special person in that she really enjoys getting to know her guests. The room was comfortable and I had everything I needed. There is also a metro stop about 6 minutes from the house, so it would be a good choice even for travelers with more time to explore the city. If you want to feel really at home, this is your place!
