On the plus side, the host accepted an early check-in, as we arrived at 10 am at her place. That was very nice. Also, the apartament it's very close to the metro station, 5 minutes walk around the corner.
On the minus side, we were in Valencia during the Fallas festival, and nobody told us that a concert scene was installed right under our balcony. So, all three nights that we stayed there we were badly disturbed by the music outside, which was playing until 4 or 5 in the morning, and it was so loud (being right under our balcony) that the windows were constantly shaking even with the blinds pulled down. Our son was crying all night because he couldn't sleep, and we also were very tired because of the lack of sleep.
