The location is terrific for real: very close to all major sites, close to metro stations (Callao, Santo Domingo and Noviciado on the red line) and all you need is just downstairs (beautiful bars, supermarkets opened till late and pharmacy). Very easy if you want and need to walk.
Mylene has been a very kind and patient host: fast answers, and super helpful.
We found all we needed in the apartment: bed sheets, paper towels, hair dryer, toilet paper, muffin, cornflakes, and orange juice! The apartment is comfortable, good and researched design.
Everything has been super: you just have to walk 4 floors ;-) (no elevator, but good to work out a bit to dispose of tapas and cervezas :-P)
Sad to leave, hope to come again!
hasta luego :-)
