We stayed at Mercedes's house for one night and the experience was perfect. The house is a traditional house with a beautiful Spanish patio. It is very well located, 15 min walking to the monument area (cathedral, Alcazar) and near typical Spanish bars, but in a very quiet street. The house is very cool, it was 32°C outside and inside was an oasis. Breakfast was amazing and Mercedes is very nice. We will come back whenever we are in Seville.
