This was a very nice expercience. Room is exactly as advertised. Spacious enough for two people. Montserrat is a very nice host. I had brekfast as well (with extra cost of only 2,5 eur).
Flat at first was a bit difficult to find but I was picked up from the spot I were in a car when I called Montserrat. It is extremly easy to get to historic centre on foot, around 20-30 min walk. I would advise anyone to eat at bars close to the flat. Especially one across the main road was rally good. With good and quite cheap food.
If I go to Seville againg for sure it will be Montserrat's acommodation again.
