The whole stay was a comfortable experience. Alejandra and Jaime welcomed us with open arms at 1 a.m in the morning and made us feel as comfortable in their home as possible throughout our stay. It's around 5 minute walk away from nearby metro stations, and just next to Retiro park. It would take 10-15 minutes with metro to get to most of the attractions in center of Madrid. The neighborhood is really quiet, apartment is really lovely and clean. I would definitely stay here again next time in Madrid, and of course, 100% recommended to anyone looking for a comfy place to stay during the trip. Big thanks to Alejandra! :)
