Casco Viejo apartment is perfect, and Luisma is a perfect host providing a great place to stay. The 2 bedrooms and 2 bathrooms were a great fit for all 4 of us. The apartment feels brand new inside and is very clean and immaculate, and it's location is in the middle of old town.
Luisma was waiting for us when we arrived, and was very kind and helpful. He had milk, orange juice, tea, and coffee stocked in the kitchen for our next morning, because we had arrived late and he knew we wouldn't be able to go to a grocery that night.
Out of the four apartments we stayed in, on our trip through Europe, Luisma's was definitely our highest ranked.
Luisma's apartment is perfection!
