Very clean. As a female travelling solo, I felt safe in Maribel's apartment. Unbeatable location wise - all the must visit spots (Alcazar, Cathedral, Plaza Espana, Triana) are within walking distance and minutes away. Also a supermarket 1 min away. Maribel is helpful and friendly, offered bfast and gave me suggestions on what to see. Just note that the staircase is on the narrower end for a big luggage (her flat is on the second floor). Pro tip - buy tickets to the top tourist spots online to skip the queue.
