Javier’s place is in a super location. I walked just about everywhere. Less than 15 minutes to palace and less than 10 to Plaza Mayor and Sol. Prado was 30 minutes, but metro and bus just minutes away. And great restaurants close by.
Javier was quick to respond to questions.
I didn’t love four flights of stairs or small Italian coffee maker.
Heating for me was not a problem, but it might be for some in colder months, especially in bathroom.
Bed was comfortable and kitchen well stocked.
I’d recommend family and friends stay there.
