Maria's apartment is a perfect place to stay, from which you can easily get around the city. Every main attraction is indeed within 10-15 min walking, 20min for the furthest areas (Triana of Maria Luisa Park). There are also plenty of bars, restaurants and shops immediately within 5min walking from the doorstep.
The neighborhood of the apartment is a local and vibrant one so it could get quite noisy at night but the double-glass windows totally isolated us from the ambient noise and allowed us calm and resting nights. Talking about sleeping, the bed is amazing. One of the best we experienced on Airbnb.
The apartment had everything we need for our 5 days trip to Seville. The kitchen is pretty well equipped and can give you the opportunity to cook yourself a complete meal if you're not fancy going out.
The overall apartment was clean and cozy and little attentions from Maria (breakfast basket and coffee caps) made our trip smoother. Really appreciated. Communication with Maria was perfect.
In a nutshell, we had a blast and totally recommend Maria's apartment to anybody visiting Seville.
