Montserrat was a sweetheart. She was so welcoming and allowed me to stay and extra day in one of the other rooms. It was a bit difficult to communicate with each other because I did not understand Spanish and only understood a bit of English, but we made it work through Google translator (thank god for Google). The flat was about a 30 - 40 minute walk depending on the speed of your walk and which path you decide to take, but it is right by the water, which makes the walk by there not so bad. I managed to walk throughout the city with no problem and if I was really exhausted the bus is only 1.40 euros. Please be aware that this place is about 1 - 1.5 hours from the airport if you decide to take public transportation, but it really isn't that difficult to get to and from there. The price was a steal and Montserrat was a great host. I hope to see her again next time I'm in Sevilla.
