It was my first Air BnB experience and the reviews were all correct.
Julian is very welcoming and helpful. The room was spacious and lockable; and it stayed cool despite temperatures above 35 every day. The flat was only a very short walk to the city centre and to the bus stop to go to the beach, Biopark and Oceanográfico (bus 95).
If you're a light sleeper like me, it is worth knowing that the room is above a café which opens very early and the walls are very thin generally so I would recommend taking ear plugs.
Thanks again for the lovely stay :)
