I stayed at Hotel Bellavista Sevilla for Semana Santa (Holy Week). The room was spacious, clean, and quiet. I definitely utilized the coffee machine and refrigerator!
I speak Spanish, but it was my first time in Seville. The front desk staff were very helpful with finding directions, helping me to recharge my bus pass, getting tickets for shows, etc. They answered all my questions with a smile and with easy to understand information. Additionally, I ate at the restaurant several times, and the food was quite good. The staff there were affable and I felt right at home.
The only thing I would note is that this hotel is about a forty minute bus ride from the center of Seville, so plan accordingly. The buses come often, but you can't just walk to the city center. The area of the hotel is very residential, though there are bars and a grocery nearby. If you want a bustling nightlife, this is not the area for you. However, if you want a quiet, relaxed, friendly, hotel, this is the place to stay!
