Natasha's apartment is clean, cute, beautiful, and conveniently located. Check-in and check-out are super easy, and Natasha is a reliable and responsive communicator.
There is a binder in the apartment with really extensive recommendations for restaurants, bars, flamenco, etc. (Go to Tableo El Arenal! It's just around the corner and worth every euro/dollar.) Anyway, this is a great place! It's on the 2nd floor (American 3rd floor), so great for everyone, barring mobility issues.
