Maria del Mar was a kind and generous host. She graciously made a quick midnight snack for the other guest and I; very unexpected and certainly welcomed!... She also prepared coffee and/or tea and a toast in the mornings. She is definitely a very friendly and talkative host. Easy to engage in conversation.
Her place is about 20-25min by bus #32 and walking from the Sevilla Santa Justa train station, about 10min on metro and about 15-20min by bus from el centro histórico. It's in the Nervion neighborhood (not a lot of tourists and very lonely at night).
Now, as far as the accommodations, I have some reservations and cannot in good conscious say i would return. Although her home and the room are very clean, and filled with lovely family heirlooms, I personally discussed the following points for improvement with Maria del Mar. Upon entering the building I could smell a fetid scent that turned my stomach. I couldn't tell if it was mildew or sewer. It immediately exacerbated my allergies and cough. I also did not realize that smoking was allowed be it in the balcony, which again was awful for my allergies. She was genuinely concerned and made accommodations to close the windows. I appreciated her gesture. But what seemed to help a bit was turning the air conditioning in the room. In retrospect, i should have found a different place, but it was really late at night and i was exhausted. In addition, the shower does not work very well; not a lot of water pressure so you get a little more than a trickle. According to Maria del Mar, she is aware if these two issues and the building is looking yo replace the plumbing to improve the water pressure for the shower. As far as the smell, she said it was sewer!, and that it has something to do with the seal of the lid on the first floor. That she had it cleaned a month ago. I mentioned to her that first impressions matter and that it's fixed, it will affect her hosting business.
As i said, Maria del Mar is a warm and kind host, who attempted to make my stay as welcome as possible despite the larger issues at hand.
