Piroska was very communicative and welcoming and yes, also very accommodating to us, not the most organized travelers in the world :-). We spent a great time in Sévilla, and we enjoyed the apartment. As other reviewers have commented, it is well placed, with easy access to the city (actually, it is in de middle of it :-). Wifi is excellent, which was useful since I had some work to finish.
Access by car is quite an endeavor, but thus is the case for the most of the ancient center.
