We had a wonderful stay in Sevilla, and a lot because of the place where we stayed.
Flavia's flat is well located (10 minutes from the Cathedral, and everything else), impeccably clean, with the comfort and everything you need for 4 people.
The flat has air conditioning in the living room - which saved us on days when it was 40 degrees outside, and despite being on a relatively busy street you couldn't hear any noise at night.
We stayed there with our two daughters for 5 nights. It was fantastic :)
There is a Carrefour three minutes from the house, with everything you need. In the near street there is a fruit shop, and five minutes walk there are restaurants, tapas houses, 'bodegas', everything you need to spend a few days in this lovelly city.
Those who bring a car and need to park, can do so in a nearby street (Miraflores avenue) for the normal price of parking, and ten minutes walk from the flat.
It was very nice!
