This is the ultimate place to stay for small well travelled groups, and I would recommend this place to any of my friends again and again. Everyone in my party found this Airbnb to be some of their favorites they have ever visited, and I wouldn't hesitate to visit again.
I found the location to be perfect, it truly is in walking distance from everything. Perfect for visiting Mercat de la Boqueria in the morning, and Madrid is so easily walkable there was no need for public transportation the whole stay. The location itself might be too tight for 2 couples, however the views from the stairwell inside the house were amazing.
This place is great for groups looking to go out and explore Madrid's culture and nightlife, however it is mindful to know it is a very quiet neighborhood so being loud is not the best idea. Another note, if you might not enjoy stairs, one of the bedrooms is lofted with no handrails for stairs, so I only recommend this place to most of the travelling population in Madrid that does not have any disabilities.
