Nestor is extremely helpful and open. He responded to all our requests and solved the issues very quickly. He met us late in the evening. We were also very delighted to receive drinks and cookies after the flight. The apartment is not in the very center (we knew it) but near different metro lines. In fact, there is no sense to live in the center because you will need to get to different parts of the city or see the main sightseeing. The flat is quite comfortable and clean. However, the beds are not very wide and some rooms are without windows into the street.
