We stayed at Pepa's place for one week. It was me, my daughter (11) and my father (70's).
Pepa was an excellent host and her place is in a fantastic location just by the Russafa market. We were here during the Fallas Festival so the entire town was noisy and chaotic (if you've never been to Fallas, plan to now), but Pepa's place was our small oasis of calm. The building is older but clean. You can hear someone's footsteps one floor up if they're wearing heels, but this did not bother us.
Beds were comfy. So was the sofabed, where I slept. Kitchen and washing machine worked well.
Pepa provided milk, water, coffee and oranges in the fridge. The kitchen was well equipped but we didn't cook at home. With the Market right there, I planned to make some tapas and breakfasts at home, but there are just too many great restaurants in Valencia — many of them a short walk away.
I should mention that the main bedroom's tub is rather deep and could be a challenge for someone with mobility issues.
