Location, Location, Location! Giulia's flat is in an ideal part of Sevilla for a walking-based vacation like the one we had. Nearby restaurants are excellent, yet the street is quiet and not choked with tourists at all hours. The flat is very well equipped, including automatic shutters and air conditioning to help beat the heat during an afternoon siesta. A small grocery store down the street can handle snacks or any supplies you may have forgotten and the cafe across the street was a great spot to stop on the way in or out if you need a coffee (or a beer).
Everything was as described in the listing and it made for a delightful trip - Giulia herself was a great host and was eager to recommend restaurants and entertainment. Her tips kinda made me wish we didn't plan our trip so thoroughly so we could take advantage of her local knowledge a bit more!
