The flat is lovely for two people. It’s a little hard to find Calle Escarpin when you first arrive. Get a taxi to the Setas. Opposite the Setas is a square with restaurants and bars. With your back to the Setas go into the square and go as far left as possible, past the bookshop, and there is Calle Escarpin!
There is a food market on the ground floor of the Setas and a Carrefour Local quite close by for essentials.
So the flat is lovely and the location is fab. Highly recommended.
