Valentina's flat is located between 2 metro stations - the red and green line are reachable within minutes and from there you can easily get to the centre. Valentina was very accommodating of our wishes, we were able to check in early since a friend and neighbour of hers was there to let us in. The flat is really cute and cozy, we felt at home right away. It was also very practical to have an instructions manual for the flat - even warning us about the neighbour's funny cats (who might try to get inside). Also, a lot of information regarding day trips, restaurants and sightseeing tips is available. The bed is big, the mattress is a bit hard/stiff but I personally prefer that to overly soft mattresses and was able to sleep very well!
Valentina was very nice to contact us in the first evening to see if everything is fine and I can warmly reccomend this flat to anyone looking for a quiet, relaxing and also homey accommodation in Milan.
