If location is what matters most, then this appartment is a very good choice since it’s within walking distance to all main attractions.
I wouldn’t recommend it, though, to people with dust allergies, since there is a lot of dust falling from the old ceillings. Since we have very young children we swept and moped the floors every day.
Also, unless you come back home very late at night, I recommend bringing some very good ear plugs, since there is a lot of noise from the restaurants and streets until at least 4 a.m., especially during weekends. Windows barely isolate any of the outside sound, since they are very old and shabby.
Raul, on the other side, was very responsive and easy to reach when needed.
