The Casa Mariscal is just an amazing place. We totally loved it and recommend it. We stayed 4 nights.
You have to be aware the metro (Buenavista or San Cosme) is 15 min walk but it worths it ❤️
When you go out, turn to the right and the next corner, you can enjoy a street juice bar with lot of local people passing by. It's also an hidden gem.
