We do not have much more to add to all the wonderful reviews that were posted by the other guests. The apartment itself is very stylish, very comfortable and very clean. It's extremely conveniently located, just a few minutes walk to everything! There is also an underground parking space if you need one.
The most pleasant part of our stay was communication with Elena (the owner's sister). To start with, it happened so that we arrived 4 hours prior to the original arrangement and Elena was very kind to rush from her daughter's school to let us in. Elena, we really appreciate that! Then, Elena gave us many recommendations on the local places. Food on the local markets was truly amazing!
To summarize, if you are planning a trip to Seville (and you should if you are not!), please do yourself a favor and stay in Ana's apartment!
