Mathias is a helpful, kind and generous host and our stay was very easy and smooth. The apartment is exactly as stated, scrupulously clean and well organised - it has amazing speakers, and the terrace is stunning. The location couldn’t be more perfect, in the thick of town but not noisy at night, and minutes walk from anywhere worth seeing (Seville is beautiful!). The only thing I wish he’d had were black out curtains in the bedroom as the street lights are very bright and for this sensitive sleeper, hard work to tolerate after a long day of sightseeing. Otherwise, the place is exactly as you see in the description, if not much better in reality. We enjoyed our stay.
