Maria is an excellent host and her place is nicely located in the El Porvenir area just outside the main tourist zone and interesting central area. The lively neighborhood has several good restaurants, bars and supermarkets only a block or two away. Taberna Autentica and Plato Plato come to mind.
The Seville historic center (Alcazar, Cathedral, Santa Cruz etc) is easily reachable with either a mile or so walk through the very nice Maria Louisa park & Plaza de Espana area or a short 2 stop tram ride from the San Bernardo station thats an easy half mile stroll through the neighborhood. If your a cyclist, by all means do rent bikes while your here and use the green bike path that winds throughout the city. It's a good way to get a broad strokes take on Seville.
Seville was a base for us and we were able to catch trains (Media Distancia) from the San Bernardo station to Cordoba, Jerez de la Frontera & Granada in 1 hour, 1.5 hours & 3.5 hours respectively. Meaning, you don't necessarily need to go to the much busier Seville Santa Justa station to get around Andalusia from here.
We were a traveling couple & this was the first time we booked a room instead of an entire house on AirBnb and it was a real treat. We stayed for 5 nights and had time to get to know Maria and her warm inviting family. Many of those great memories of this 2017 Spain trip will stay with us forever. If your the kind that relishes opportunities to meet, converse and make friends with other international travelers than this is a great option in Seville.
It's a very nice character, secure, large multi story house with several rooms that are rented out. We booked the "Centro Estudio with terrace B&B Verde" which is on the 2nd level with an En Suite bath and away from the street. The included private patio proved to be a great place to lounge around and enjoy in the cooler evenings. To me it was one of the best values for accommodation during our entire trip. In addition, Maria not only made breakfast several times during our stay and was a welcome start to many of our days here, but also did a load of laundry which was a huge time saver.
Maria is simply amazing. She is a very hard worker with a big heart, and a host who does everything in her power to make her guests comfortable and welcome. She is mostly a Spanish speaker but does speak some English (at least with me). In the end I totally recommend that you stay here in Seville, not only for it's great location, easy access to the sights & community feel but also for the opportunity to spend time with a great family in a real Seville home atmosphere.
