We loved the apartment especially the location. It's a very popular area but very nice, 10mn walks from the main places to visit. Isabel sister welcomed us and she was very nice and welcoming. The neighborhood is relatively calm. It's perfect for 2 persons.
If you are coming by car and need to use the parking (which is approx. 10mn from the apartment but still convenient), you have to add 15 euros per day which is not clearly say in the description.
Besides this, it was perfect and I recommend you to stay here to visit Sevilla.
