The building is very old and tatty but the apartment is well maintened and well-equipped.
The only thing negative was the thermostat (faucet) to regulate the temperature of the shower. Need to be changed because the hot water temperature was not very hot - a little bit just/cold from my side (even if we turn it at the maximum).
It is annouced 1.5 bathroom in the description, but there is only 1 bathroom with shower. Toilets are separated from the bathroom.
The street is calm.
The nearest subway station is very close - 5 minutes walking from the apartment.
A supermarket is also at 5 minutes (very large opening hours).
And we went twice to the restaurant called "Bodega Monumental" a lovely traditional spanish restaurant (with lovely tapas and good paellas).
Francisco was very reactive in his answers.
