3 days in Seville Oct 10 to Oct 13.

Popular attractions include the Alcázar, cathedral, Giralda tower, Torre de Oro, Plaza de las Américas, María Luisa park, Barrio Santa Cruz, Metropol Parasol and Triana neighborhood. Most of the places are within walking distance. One can walk to the Triana neighborhood but it is a little further away. On our last visit there we stayed at Hotel Amadeus, about a 5 minute walk from the cathedral. If you’re interested in bullfighting there are tours of the bull ring, but with only 3 days it wouldn’t be top on my list.

In 2017, we really enjoyed the Hotel Becquer - the Amadeus was more expensive, and full. We walked everywhere, and it is extremely convenient to the Triana neighborhood.

Rick generously lists what he considers the top attractions right on this website:

However, I highly recommend buying his guidebook to Seville, Granada and Southern Spain for additional insights. If you're traveling more widely in Spain, the "Spain" guidebook would be a better choice.

Hi coco, when I was in Seville I stayed in the Barrio Santa Cruz that’s known as the Jewish Quarter and was within walking distance to the top sights. I suggest buying Rick Steves’ guidebook too that’ll list hotels and what not to miss seeing while there. For Rick’s hotel listings you can check to see if there are negative reviews in TripAdvisor.
You should also check out Airbnb rentals in the Santa Cruz section of town. If you do book through Airbnb, make sure you book with a super host. I’ve read stories about those who didn’t and had their reservation revoked.
The one thing Seville is famous for is flamenco. Rick’s book will list places for you to go and watch a performance. I highly suggest taking his self-guided walking tours so you don’t miss seeing anything. Enjoy Seville!

I would suggest a flamenco show. I preferred the non dinner options. Not sure when they will reopen for business, however.

Personally, I find flamenco slightly less enjoyable than someone scratching fingernails down a blackboard. But grima as it is, it is also traditional so worth seeing once, but only once. I think the suggestions you already have will fill your three days, but as additional options, I'd add the Casa Duenas and Pilatos.

I usually stay at business hotels which might not appeal. But in terms of location, I would suggest seeing how far your hotel is from the cathedral. If it is just a few minutes walk, then you are pretty central for the main tourist sights and the tram.

Nick, that's why I took the one hour non-dinner option.....and the small venue I chose. I wasn't sure I could manage it. Dancing was great, but I am afraid I am not a fan of the mournful songs. I won't be visiting a Fado performance....

I am a man solo traveler. On my other 4 solo trips to Europe, I stayed in hostels when available, the kind of place where solo travelers and sometimes groups of friends stay, to save money, where you share a room with strangers. For my trip to Spain in October, so far I have choosen all hotels. I have been using booking.com to find and reserve hostels and hotels. On booking.com, searching for "guesthouses" will show the low end hotels known as hostales. I don't use guidebooks to find hotels. I try to buy most of my food in grocery stores or markets. To me the only excuse to spend money on restaurant food would be if I was my family or friends and we had no other place to sit and talk and/or if ths weather was just too cold, rainy, or stormy to eat outside or if there was no cafe in a museum or lobby where I could sneak in eating food I had bought at a market or grocery store.

After Rick Steves, another good guidebook is "The rough guide to Spain", and possibly the "Lonely planet guide to Spain".
