I fully recommend Francesco's apartment! The flat looks like in the uploaded pictures - you can find there nearly everything you may need during the stay. There were beddings, sheets, towels, availabels, as long as the kitchen equipment (dishwasher, washing machine, oven, glasses, plates, cutlery etc.) and some may be happy with hair dryer as well. There is also air conditioner in the flat (can be really useful sometimes). The apartment is not located in the city center, but it definitely is not a problem - the communication with the city center and other districts is great thanks to the underground (3 minutes walk) and the RENFE trains (direct connection with the El Prat airport).
Near the apartment you can find supermarkets, bakery, fruit market etc.
It took us ca 25 minutes to get to the beach with slow, holiday walk pace.
Communication with Francesco was smooth and he answered all our questions before the arrival and during the stay.
To sum up, we were very happy with the apartment and the stay itself, you'll be too! :)
