Carlo was very kind and helpful. At our arrival, we asked him to bring us a vacuum cleaner, a big pan, which he did without hesitating. He also took time to advice us what to see in Valencia. The flat is found in a rather old building with a small entrance and small stairway. On the first floor of the building, the flat is well renewed and comfortable with air conditioning in the living room. It is big enough for 8 persons to sleep but need to queue for the shower and toilet, the two are in the same bathroom. The appartment is located near train line #4, which gives easy access to the town center. The drawback is the noise it brings, but the train stops at around 11:30 - 12:00 PM, and so was not a problem for us. The neighborhood is quiet and parking place is free and very easy (so as for all València city).
Thanks again Carlo for your appartment and your kindness.
