the position is perfect! the neiborough is very quiet, but cool. the house is very close to teh Lavapies metro and museums' area (Reina Sofai, Prado etc). easy to get it.
you get Puerta do Sol in a metro stop.
the house is small, but is not a problem for a short holidays.
there could be sone better accurated details; we didn't find a shower soap or a bottle of water. maybe it have not to be provided, but coul be kind for guests.
the apartment has a good heating and realy silent. some details coulb be more accurated.
overall, we had a good time in Madrid (the city is beautiful) and at Eloisa's home
