We really liked an apartment, it was clean and cozy. Bedroom's location was perfect and each has its own bathroom and toilet, so it is very comfortable for a group of people to live there and have some privacy.
Location of an apartment is good, you can find a lot of restaurants and cafes around and from there you can easily get to historical places.
Big thanks to Mike, he gave us good recommendations and provided a list of information that was extremely useful for our trip.
