I would definitely recommend staying at Concha's flat in Cabanyal. She has furnished the space perfectly with everything you need and more. The space is actually much larger than it looks in the photos too. Communication was perfect. Concha responded at midnight for our request to move in the following day – we were in an Airbnb that ended up being way too loud and she was super accommodating receiving us last minute.
In addition to extremely comfortable beds, both bedrooms are located in the back of the space with shutters making sleeping a literal dream. You can't hear any sounds from the street despite the fact that you are located in the heart of a very lively area. The apartment is close to the beach but also a 10 min walk to El Cortez Ingles and less than a 2 min walk to a huge grocery store.
One last note, I think Concha's flat was probably the cleanest Airbnb in which we've ever stayed. Absolutely spotless. Will definitely stay here again!
