I had the pleasure to stay 4 nights with Silvia and loved every second! Here are some of the things that made the stay special:
Location: The studio is located in a very fun and exiting spot, lots of winding streets, a beautiful market, great restaurants and tapas places, small cool shops, very near the Macarena Gate and the Hercules Square where all the night life goes on. This is where the locals meet. Major sights like Alcazar is just a 20-30 minute walk from the apartment so you do not need bus card.
Studio: The studio is beautiful, and Silvia has decorated it so nicely, it makes you feel at home. There are all the things you need, and the bathroom is modern and beautiful. Bed is really comfy, and the window to the street is unique. As the studio is next door to Silvia and the entrance is shared it feels really safe.
Silvia: Is so welcoming, she immediately gave me a map, pointed out the must sees, gave great suggestions on what to do, and also arranged a Flamenco show in the tiniest theater I have ever seen, located in a really cool spot.
All in all I highly recommend you book with Silvia for your Seville stay!
