I stayed at Elsa's apartment to catch up on some sleep after a long flight from Miami. When I arrived, I was greeted by Gustavo, who joined me in having some tea and a thoughtful discussion. Their apartment is a short distance from the airport, though I don't recommend taking a taxi. I would suggest taking an uber from the airport instead because of the price. Gustavo talked with me about the best places to visit in Madrid. The neighborhood looks very safe. If you get lost (I did get a little lost because of brain fog due to long travel) people are very kind and will try their best to help you. During my stay, everything was pristinely clean and nice. Thank you to Elsa and Gustavo for a lovely stay.
