I have so many nice things to say about this flat. But for brevity's sake, I will narrow them down to 2 points:
1) The actual apartment: spectacular. As a single woman traveler, I was concerned about basic safety as I was abroad for about 3 months alone. The double gate set up really put me at ease. The apartment is also centrally located and in walkable distance to a grocery store, many eateries, transportation depots, and tourist attractions! The furnishings, the hot water unit (a must for me), and the general ambience (quiet, peaceful) were all perfect.
2) The hostess: Sandra was phenomenal. After a very hectic string of flights to Seville (and after Iberia LOST my luggage), I was beat. Sandra greeted me with so much kindness. She walked me through the apartment, showed me the toiletries she had on hand, and then proceeded to walk me down to the shops to show me where I could buy pajamas! She left me detailed notes on how to reach the local beaches and even commented on which beaches would suit the vacation I was looking for ("kid friendly" "youth friendly" "less crowded" etc.). She even let me know throughout the trip if she was going to be away in case there was a lapse in communication. I cannot overstate how warm, accomodating, and knowledgeable Sandra is. The perfect hostess. She really made my trip wonderful.
Staying in Seville? Choose her place. You will not be disappointed.
