Gary is an attentive host. His apartment is truly a quiet oasis in the midst of a central, busy, nightlife-rich part of Seville. We are a family of four, our kids are young teens. The central location and it's quiet meant we would go out for a few hours, then come back to recharge, then go out again. Sometimes with, sometimes without or kids.
We slept with our windows wide open (it was late October) - the windows open on to the common courtyard. The only noise was the occasional other residents of the apartment complex walking through the shared courtyard at night or in the morning. I was surprised no other windows were opened, we heard no other residents.
Although the second bedroom has two beds - one is a trundle bed (pull out) - our son (12) decided to sleep on the sofa in the living room. Sleeping arrangements worked out fine.
