We had an absolutely fantastic stay at Antonio's place!
We had some specific requirements as we were working remotely from Seville, and this apartment met them all. Enough space for two people to work and live comfortably, a fast and stable internet connection, and an incredible location to explore the city from. The building has two exits - one on the street side, one on the riverside - and it was amazing to be so close to the water while also being in the heart of the action in Triana.
Bonus points for communication: Antonio checked in several times to make sure everything was okay, he even offered to arrange an extra table for us to work (which we didn't need in the end because the apartment was already excellently equipped), and he was super quick making us a new key when we realized that one of the building keys wasn't working.
Incredible place, a definite recommendation when staying in Seville!
