We warmly recommend Ben's place.
We spent there 5 days at the beginning of January.Ben's place is a studio (exactly as it looks in the pictures) equipped with everything needed, clean, cosy and, very important for the winter days, very warm. It is within 20 minutes walk to the main attractions and there is at least one busline direct to the museums and palaces. There are 2 supermarkets very close.
Ben is very helpful and available.
