Myself, my wife and our 2 year old had a superb 4 day stay in this apartment. Location-wise it is excellent, just a minute across the road is the Jardines de Murillo and you are in the midst of lots of tapas bars and restaurants within 5 minutes. The wonderful Calle Mateos Gago, the Cathedral and La Giralda are about 10 minutes walk through Seville's classically beautiful winding streets. Plaza de Espana (well worth a visit!) is about 10 minutes in the other direction. There's also a Carrefour about 5 minutes away should you need it, and a great juice bar called Jester also 5 minutes away.
The apartment itself is quite functional but very clean and tidy. The living space is a good size and it has two spacious bedrooms and bathrooms. It has everything you need for a short stay. It would be comfortable for individuals, couples and small families. The communal rooftop pool is a particular highlight and can be accessed by going up an extra flight of stairs.
Macarena was easy to communicate with and we had a very enjoyable stay. Seville is a stunning city and this apartment is a fantastic base to see the city from. Would recommend.
