Our stay in Maria's place was perfect. The room was very clean (as well as the bathroom) and well furnished. The bed was super comfortable! Maria and her daughter were lovely hosts. The house is well located, it is not in the heart of the historical center, but in a quite neighborhood very close to Plaza de Espana and San Bernardo station is 10 min walking (Airport shuttle). Recommended!
PS: the cake we had for breakfast was delicious :)
