Alex has been a really good host. Even though the check-in time was at 4 p.m., he arranged to meet us before, at our arrival. He showed us the house and explained basic practical issues. He also have us some advice on how to keep our luggages the last day, in order not to have to visit the city with them.
The house was really comfortable for a group of seven people like we were - just a little noisy the other apartments, because it is an old building.
Overall it has been a pleasant experience.
