Manuel's place was as described and shown in the photos. It is in a great location. We walked to all the Sevilla highlights from Manuel's place. Manuel was also a great host, giving us a detailed overview of things to do, places to eat and visit, even offering to call places and make reservations on our behalf. He genuinely loves Sevilla and wants to share his passion for the hometown with his guests. (Ask him about Triana!)
The one tip I'll give to prospective renters is that the apartment is in a central location which means there can be a lot of noise from the streets. We heard cheering from the streets during a football match and trucks in the morning servicing nearby restaurants.
