Natalia's apartment is tastefully decorated, very clean and central. It is located on a street where you can literally do a tapas hop on hop off in the various restaurants on the street.
There are mobile heaters and an airco in the flat; therefore well prepared to heat and cold.
The only disadvantage is that it is looking at an internal patio; but you are out all day long so should not be a big problem.
As a host, she has been very helpful and flexible before the arrival with making sure that we have the keys despite our late arrival. Unfortunately we could not meet her face to face.
All in all, it is a neat, well located place and at the heart of the city.
