Many thanks to host! The flat is amazing! It's huge, consist of many rooms, two bathrooms, long corridors, kitchen and a hall. A lot of antique stuff...no, it's incorrect words, there is nothing except for bed linen that is not antique! :D flat was clean enough, and everything was in there.
Beautiful street and district just near the city center, everything was perfect! Just 20 minutes by feet from the plaza del Sol, and 15 to plaza Major, 10 to royal palace and opera house. Very clean area, a lot of flowers, trees, places to sit and to eat, etc. Few supermarkets nearby.
I'm strongly recommend this house, and hope to come back one day!
