Eduardo is a perfect host, he helps in anything you need and replies very fast for all questions.
The flat is at a good location, the city center can be reached by walk. There is a medium size supermarket just 2 minutes walk, a vegetable market around 15 minutes walk and the metro station 10 minutes (if you walk slowly). From this metro station you can get strait to the airport.
In the flat you will find everything you need, you can even cook for yourself is you wish to.
The bed was different than the one shown in the photo.
There is no air conditioning, I had no problem with this but the weather was not very hot this time, so the temperature in the flat was ok, also there are shades for the windows which you can close for the day so the flat will not get extremely hot (as the sun shines in during the day).
The only issue I had that I could hear everything the neighbors did in the flat above me. Flashing the toilet, talking with each other, taking a shower and other things I really don't wanted to hear...
