Mercedes was so lovely - the perfect, hospitable host! She had a bowl of sweets at the top of the staircase. Breakfast was laid out every morning of very yummy things - cheese, ham, eggs, bread, smoked salmon, avocado - it changed every day, but was always of high quality ingredients. Her terrace is amazing! It looks right over the Square - very nice views. There are restaurants everywhere. Very easy to access everywhere by foot. The 6 flights of stairs were difficult with a 30kg luggage, but very easy without the luggage. :) A very enjoyable experience and host.
