We just finished a three week stay in Angel’s apartment. Overall, it was a good stay. The location was terrific, especially for trips outside of Madrid by train. Not only is it less than 3 minute walk to Atocha, the neighborhood has everything you need for a good stay. Grocery stores, bakeries, fruit/veggie stands, restaurants, parks and metro are all convenient. It is also very close to major museums and other tourist sites.
The apartment itself is very large. The bathrooms and kitchen have been updated recently but the rest of the apartment could do with a refresh. That said, it was clean & comfortable with good beds, plenty of seating, and a well stocked kitchen. There a bit of noise on occasion from other apartments but that is to be expected. It never interfered with our sleep.
Communication with the host was excellent, probably the best we’ve had with an Airbnb host. If our travels return to Madrid, we would consider staying here again.
