I stayed at Berta's for a long time while I worked in Seville, so I got to know the property very well. I'm very glad I was able to stay here long-term and would certainly do so again.
Overall, it is a comfortable and good-sized apartment located very close to public transit, grocery stores, restaurants, bike paths, scooter parking, and city parks. I would probably classify the apartment as young professional and family housing, so you get a typical experience of living in Seville, but outside of the touristy center. It is easy to walk to the main Triana restaurant area...probably about 10 minutes on foot. Walking downtown is easy as well. It took me between 15 and 20 minutes to walk to the Cathedral. I bet it's about 45 minutes on foot to places on the northern side of the touristy zone, but you can also take public transit. If you're lucky, Berta might even have a bike available for you to use. Rentable city bikes can also easily be found.
When I arrived, Berta met me and was very helpful with a tour of the apartment and a crash course in what I needed to know about the place. She was great with communication throughout my stay and always responded unbelievably quickly if I needed anything. She had great recommendations for the city. The apartment was clean, and the kitchen fully stocked for whatever cooking I wanted to do. The internet was fast. I was always able to video chat with people back home. When it came time for me to leave, she was helpful in providing check out information and routes to the airport at an early hour. She was also very helpful when my itinerary drastically changed. I appreciate the support she provided throughout my time there. Most of all, I will remember that she was a delightful person.
To be honest, I struggle to find anything critical to say. It might take you a little time to get used to some of the quirks of a real Seville apartment, but I got the hang of it quickly. If you need an apartment to be totally silent all the time, be advised that the place overlooks a busy road, so there is traffic noise in parts of the apartment, plus normal city apartment-life noise in the building. If you have limited mobility, the stairs and the shower may be difficult for you.
But overall, I had a great experience. It would have been difficult to find a place with a better value or a more communicative host. I was sad to leave. Thanks, Berta!
