The stay at Teresa´s and her husbands home was awesome. Both of them were great hosts and when we arrived, Teresa even waited until our arrival around 1 o'clock in the morning to let us in. The communication in the forefront and also during our stay has been via WhatsApp and Teresa replied very quickly and responded to our requests.
The room was simple but had all that it needs for a stay to discover this beautiful city. The place is located a little bit outside the city centre but given that Seville isn't that big, you could reach nearly all crucial sightseeing spots in walking distance.
Summarised, we had a perfect stay at Teresa's place and I could fully recommend it for a stay in Seville.
