We stayed at Marta's for Santa Semana and I am so glad we were in Seville.
The location of the apartment was safe and great to walk to all the sites. Javier, who greeted us, picked us up at the train station and helped throughout the stay was and was basically our concierge was outstanding!
The apartment though was a bit disappointing. It's smaller than the photos show, basically a room with very tiny kitchenette (which could use new pots and pans) and the couch was really uncomfortable. The design though is very nice.
The shower is very tight -if you turn around, you got the faucet and the water goes extra hot or very cold. The tank is also minuscule so chances are if you are second in the shower 2 minutes for warm water is the max.
We had issues with finding the drying rack, which was under the mattress - -wouldn't have looked there, but Javier came over and found it, and the washing machine door got stuck - really stuck, and Javier was able to open it -- it stuck again the next time we did the wash so if you stay here, beware.
We loved the courtyard outside the apartment as well.
Around the corner and down the street a bit is a nice cafe and bakery for snacks, breakfast and a light lunch. We also found a nice breakfast spot called salt and sugar close by.
I think there are a few airbnb's in the building - some might be larger so have a look.
On the whole Marta was very nice to communicate with and Javier was very helpful - even arranging tickets for flamenco and taking us to the rental car place for a fee.
The flat will accommodate two for a short stay and hopefully, the kitchen, washer and bathroom will be worked on a bit.
