Elena's apartment is centrally located in Seville near the Triana Bridge and roughly 2 miles from the train station. Our train from Madrid arrived at 11:40a and Elena accommodated my request to check in early - meeting us at the apartment so we could drop off our luggage before going to grab lunch and start exploring. There is a small grocery store about a block away where we bought breakfast necessities. The Mercado Lonja del Barranco is less than a 5-minute walk and offers several food options. The Triana district is just across the river; the cathedral is only a 15-minute walk away.
Elena's apartment is very clean and spacious. Each bedroom has a ceiling fan in addition to AC units. There is a smart TV in the living room with Netflix - you can use your login and password if you're a subscriber (be sure to logout before you leave). The building has two entrances and an elevator. The area is also safe and quiet - we never heard any of the other residents. Elena was quick to respond to any message I sent. Lastly, her apartment is the closest to a U.S.-size and style apartment that I've stayed in while traveling in Europe.
I would highly recommend Elena's apartment for anyone traveling to Seville!
