In Milan center there are excellent accommodations even for less than 70 €. How do you say? Don't believe it? Nothing easier if you want spend little and sleep a stone's throw from the city center.
THERegency Hotel in viale Valassina offers all the comforts of a 4-star hotel, with 70 rooms equipped with telephone, satellite color TV, parking, internet and so on and so forth. A double room costs € 90 per night, a single room only 70€, the breakfast room is very nice but in general the furniture is a bit old, maybe just elegant.
My favorite is theWatttredici hotels, a few steps from the Navigli is comfortable and very modern, personally the type of accommodation I prefer. The single room comes 69 euro per night, double 79, but it deserves them all, a truly hotel with all the trimmings.
There are many other hotels in Milan worthy of note but for now I have focused on these two, in my opinion cheap and very central, according to you I could find better for a 4-star hotel?
A tip comes from Michela, she found a really nice b & b in the center of Milan for only 75 euros per night in a double room. The b & b Milan the 2 Navigli it's really very nice, thanks Michela for reporting.
