3 people - 1 couple (60, 68) and 1 single (30). 13 night stay in October 22, arrival late Monday and check-out Saturday morning.
Juan and his daughter are lovely, were very responsive to communication and very accommodating. She can speak English (and maybe other languages) so will do most of the talking, but the translate feature on the airbnb messenger will do the trick for those of you who don't speak Spanish.
The place is (much) bigger than it looks in the photos. There are 2 bigger bedrooms (1 double, 1 twin) with loads of wardrobe space. There is a further single room with desk space. The beds were comfortable and there was plenty of bedding and towels provided. The kitchen is big and has a washing machine; and the bathroom is a comfortable size. The water pressure in the bath/shower is just about good enough. There's a thin balcony, with just enough depth for 2 to sit facing each other - one with a good view of the Torres de Quart. The flat is on the 6th floor (5th for Brits), so the balcony isn't for the very faint of heights. There is a lift to take you up and down the stairs too, which you'll really appreciate.
The place is in a great location, right by the east gate in the old town. This makes it perfect for sightseeing - all of the main Ciutat Vella attractions, bars, markets and restaurants are within 10 minutes walk. There's also a Valenbisi bike rack about 2 minutes walk - perfect to cycle along the linear park to the Ciutat de les Arts i les Ciències, and onward to the beach. There is some noise from the street into the early hours, particularly Friday and Saturday, but shutting the windows solves that. Valencia is also a place that seems to run from 9am-1am, rather than, say, London's 7am-11pm; so best to acclimatise if you're here for a while.
The place does have an air conditioning unit in the living room that says it'll get you to 20C, but I found I was still too warm (outside temp c. 19-26), and needed to use the one big fan provided. There is no wi-fi - I was here to try somewhere new while remote working, so I booked a co-working space called Garage just down the road that was fab.
