We spend 3 nights at Seville- good communication in terms of arrival info . We were welcomed by a young girl sent by Ignacio to show us around the flat and who helped us to access the underground car park (tight with long car but OK).
The flat is within 10-15 minutes' walking distance of the main Seville tourist area in a quiet (one-way) street. Very conveniently located.
Overall flat was clean but smaller than expected: just enough space for bed in bedroom, no window to the outside (only bathroom window to inner courtyard and "outdoor seating area in a "shaft") but as we did not spend much time there, it was ok but would hesitate to recommend it for a longer period . Good internet connection.
