Nacho's apartment is amazing. It was super clean and very modern.
The mattress and pillows were super comfy! I have not slept on such comfortable beds and mattresses in 5 star hotels as well.
The location was perfect as well.
He was very proactive in all his communications and his colleague gave the best advice on what to eat and where to go. Their recommendations were wonderful. I would definitely stay at his place again once I come back to Seville.
