This is a brilliant place to stay in Seville. Comfortable beds and pillows. Air con and heating in every room. Unbeatable location near supermarket, restaurants, Alcazar/Cathedral (and easy walking distance to the train station, river, park, art museum and shopping district). Internet and Netflix. Well-stocked with everything you might need. Fast communication from Astrid in English.
We visited with two young children, and Astrid had provided a high chair and toys. The flat was very child-safe (and well worth bringing the pushchair to the second floor!).
