Maribel’s place is very well located a couple of meters near Goya street at Salamanca neighborhood. Has two subway stations nearby (without subway stations’ inconvenients) and close to the bus station that takes you to Barajas airport.
You can move anywhere in Madrid from there. Also, has nice cafes, bars, supermarkets and El Corte Inglés around.
The place is comfortable enough you can stay there and enjoy. And our host was very kind to show us all details from it.
Good recommendation if you want to be in a great location without upscale prices.
