The first point is about the location: absolutely wonderful. It is at the midpoint of a triangle bounded by three different Valencia Metro stations, each serving different lines, and each quite close: one block for the one out to the Port and the beaches, about three for the line that runs north and south, and four short blocks for the one that runs directly from and back to the airport and right thru the commercial heart of the city - at most about 4 minutes away. Heading out in different directions, this makes metro traffic to everywhere incredibly convenient; and, with a TUIn card, very cheap - usually only 80 eurocents per ride.
Second, the immediate neighborhood is the edge of Valencia's small Chinatown, with a large variety of inexpensive Chinese restaurants and food market stores. Among those stores is one quite large Chinese market store a half-block away from the lodgings, close enough to make lugging a 6.25 gallon jug of water tack to the apartment an easy errand. The nearest full-range major large-scale supermarket, one of the Mercadona chain, is about four short blocks away, with most everything that a traveler might need by way of food and drink.
Third, the lodgings are impeccable. This is above all due to the well-restored interior of the apartment, and to the wonderful work of the person who keeps it clean, named Sula. The prices for the four different rooms vary according to their various provisions, but in general they seem to be both low enough to be good bargains but high enough to somewhat price out most short-term visitors coming only to drink at local bars late into the night.
One clarification beyond what might be inferred from the descriptions of the units might be helpful. There are four different units, and each has a double bed, meaning that there might be as many as eight people in the apartment at the same time, though during my stay in one of the large rooms, there were normally about three or four other people, all of whom behaved like adults conscious of appropriate behavior in a shared lodgings; but this could just be my good luck of the draw.
Communications with Renato were always crisp and clear. One suggestion is that provision of the exact street address and apartment number should be included in the confirmation letter, as is the case in every other Airbnb booking that I have ever made. Waiting until that information either is requested in advance, which I did, or until 48-24 hours in advance, creates risks of trouble in case of any breakdown in access to communications, which I personally suffered due to some completely unrelated problem with my internet service provider.
Overall, a great location, great lodgings, and fully responsive staffing; a fine value.
