We have visited Seville 27th-30th of December. We used Uber to get from Airport to apartment it took us around 20min and cost €15. We arrived early and we were given an opportunity to drop our bags before checkin time. Hosts are very friendly and full of recommendations what to see or were to eat. Communication was great from start to finish Manolo doesn't speak in English(his wife does) however we still didn't have issue communicating with each other.
Apartments is clean and has everything you might need. Distance to city centre is good 10-15min walk. We have walked everywhere on foot and didn't have to use any public transport.
Loved Seville and it was a pleasure to meet Manolo and Maria :) I wish them all the best in a future and highly recommending their place to everyone visiting Seville.
