I had a great stay at Manuela's place. The flat is well located, just off the old town, within walking distance of all sights and close to the train station and bus stop to airport. The flat itself (and my room) was clean, warm and comfortable.
The highlight was Manuela, an extremely warm hearted, friendly, open and uncomplicated person who went out of her way to make sure I had an enjoyable stay. This included the collection and sharing of tourist information and restaurant / food tips, offers to share meals and drinks together, and a general interest in me and how I was enjoying my stay. I couldn't recommend a stay at Manuela's more. Your stay in Seville is enhanced by doing this.
