Alberto is a wonderful host. He picked us up from the bus station and took us to his flat. When we asked for recommendations, he sent us a long, thoughtful list. He has some nice touches for guests to use during their stay like maps, chargers and adapters.
The place is a bit far from the city center, you'll want to take the bus or metro, but both are very close to his place. In the evenings, we took the night bus back and it dropped us practically at the door.
The flat is bright, clean and full of everything one might need. We only spent two nights there, but it would've been a good place for a longer stay with air conditioning, laundry, and a very comfortable bed.
If we're back in Sevilla, we'd return to stay with Alberto.
