We stayed 4 nights at Nati's apartment. We were satisfied with our stay there. Communication with a host was good. Nati lives at the same apartment but she was a very warm and welcoming person. We didn't mind when she was at the house etc.
Everything was clean inside. We could use kitchen without problems, there is a lot of accessories if you want to make your own meal. The room that we stayed in had an AC which was an advantage, especially during our stay in Sevilla ( it was really hot !).
The apartment is located in Triana district, it's 30 minutes away from city center by foot. The closest metro station 10 mins away. It was a bit too far away for us. If you are not scared of long walks (even when you're tired and the metro is already closed) then it might be for you. There is a bus stop somewhere near apartment but we didn't check it. There is a problem with a shower ( water tends to flow outside so you have you mop it every time). Apart from that everything was fine. I recommend !
