Teresa's apartment in Seville is very comfortable and has a great location. One is very close to the Cathedral and Real Alcazar and tons of the restaurants. The apartment was as described and the host was very communicative. They created a whatsapp group to communicate details regarding check-in, check-out which is a very efficient.
I wouldn't recommend keeping a rental car in Seville, as the old city is very limited in terms of parking options. Everything is walk-able from the apartment. If you driving up to the apartment to drop luggage, things can be a little tricky as there is a Starbucks with taxi parking which is the only option to park a vehicle for 4-5 minutes. The Starbucks is very close to the apartment. Using taxis is a better option if you are arriving at the airport or the train station.
