There is a mix of good and bad things about this flat.
The duplex is in a perfect location, Santa Cruz, which is a very nice an athentic neighbourhood in downton Seville, very beatiful and nice to walk around. Close to the Alcazar and the Cathedral.
The duplex is nice, there is no elevator, as probably in most apartments in the area, but there are no many stairs. The flat is nicely decorated, it is clean in general, wifi works perfectly, there is AC in most rooms and works very well. Check-in was also well organized.
The main issue was with the toilets. There is a strong sewer smell in both bathrooms. Although they are trying to solve it with automatic air fresheners, this is not enough and the bad smell is strong. I think this should be mention in advance as this, in a hotel, would be a reason to change room inmediately. We were there for a few nights and didn't complain, so this is something you can live with but a bit disgusting, and not something you expect for this price.
I think also that the stairs to go to the terrace are very steep, and the terraces are small. We didn't spend time there and I think that the photographs shoud be a bit more realistic.
