I spent three weeks in this apartment, and it was a fantastic place to stay. The apartment is very cozy and comfortable, and has everything you need for your stay in Sevilla. The location is very convenient, with the big tourist sights (Cathedral & Giralda, Real Alcázar) and tourist & shopping areas all within a 10-15 minute walk. There are a couple of tapas bars right across the street, and many more within a 5 minute walk. There are also several grocery stores nearby so you can stock the fridge easily.
And Raquel is very friendly and warm-- she even brought me a couple things to help me when my luggage was delayed for a few days because of a big airline glitch!
I couldn't have asked for a better experience with Raquel, and I'm planning to come back and stay here again in the future. Highly recommended.
