This flat is on a great location. Very near Puerta del Sol and downtown in general. All within walking distance.
It’s also very close to the train station and the Retiro park. If you’re a runner you will appreciate that as I did.
There’s a supermarket nearby and many small ethnic fruit stores.
The place is very clean and for me was great. Alfonso was very nice and welcoming. The apartment doesn’t have any toiletries just keep that in mind. As a whole, a great place for solo travelers or couples.
