Carlas flat is beautiful and very comfortable.
Its perfectly situated if you don't want to be in a busy shopping street but still close to the centre.
The metro station is like 5-10min away (on the E Line direction to the airport) and you find bakeries within a few minutes walk.
Carla and Carlos were lovely and filled the fridge with some food as my flight was delayed. As the temperature dropped they brought me two heaters, that was very nice.
I highly recommend this flat and would come anytime again.
Only minus point, the other flats are rented to tourists as well.. if you are lucky like me they are having a party every night...but with earplugs it was tolerable.
