I cannot recommend any specific guitar shops, etc, but we really enjoyed staying at the Hotel Amadeus in Seville. Following is my review of the place:
"This was the most expensive hotel we stayed in during our three weeks in Portugal and Spain, and was also one of the most enjoyable because of the great location and because I could borrow their guitars. Our room was a double with balcony. They provided two cots w/o charge for our 8 and 12 year old children.
The room was large, clean, comfortable, and nicely decorated. We were in the "La Musica" part of the hotel, which is adjacent to the Amadeus portion. We had full access to both areas. I enjoyed the piano room on the main floor of the La Musica. This room is soundproofed and you can play the piano. They also have violins, guitars, harps, and accordions that you can borrow and play. Most were in unplayable shape with missing strings. There were three working guitars, one of which I fixed the strings on, and was pleased to borrow as I was feeling withdrawal symptoms after being away from my guitar for three weeks.
Breakfast was good. We bought two breakfasts each morning, which provided sufficient food for two adults and two kids. The rooftop patios on both the Amadeus and La Musica were nice. The front desk staff were pleasant and helpful. Parking in the recommended parkade was an easy 200 meter walk from the hotel. The hotel's location is superb - about 5 minute walk to the main restaurants and the cathedral."
We went to a Flamenco concert at the nearby "Flamenco Casa de la Guitarra". It was okay, but I've seen better shows in Canada and had better guitar experiences in Granada (e.g. the buskers at the Mirador Saint Nicolas in Granada). However it was worth going to for lack of a better place. We reserved seats early in the day and had a great view. The place is small and intimate and it has numerous "historic" guitars lining the walls that were interesting to see.
Restaurants were a bit of a disappoint to us in Seville. The meals were okay, but the restaurants didn't have an enjoyable ambiance. Too touristy perhaps in comparison to our experiences in Granada. The cathedral was spectacular and we seriously enjoyed the ~1 hour long horse drawn carriage ride that was offered by many vendors right beside the cathedral. There is a small guitar shop/museum located on a side street steps off the main cathedral square - where I bought guitar strings - but other than being proud of ordering the strings in Spanish, I cannot say the shop/museum was much to see.
