I give Mattia five stars in all categories, with the exception of the following four star ratings:
Cleanliness:
Some hair in the shower.
Size / noise:
I guess flats always look bigger in the pictures than in real life.
Now, if you are a large person you will have a problem with the shower cabin and with the narrow ladder up to the loft bed (the second bed, not depicted).
During nights we heard some noice from the neighbors and around 6.30 am from the dust-bin collectors.
Location:
The place is at a ten minute walk only from the Atocha station, which is great. There are bars and restaurants in the neighbourhood were you can get inexpensive breakfast.
The main street --Ronda de Atocha and the surroundings -- is not really an interesting area for a stroll.
If you continue up the Amparo street into the Lavapies area the area and its inhabitants look seedy.
