Olga and her daughter were lovely and we appreciate their hospitality. I'm sure they will help you with everything you need.
The apartment is beautiful, well located, and the room is comfortable after a long day in the city.
Two things that you should consider. First, there's one block of distance from the subway to the apartment. It's an uphill street and you will have to use the stairs inside the building. Second, there were 3 pets and a strong smell in the common areas. The room did not smell at all.
Both things you may adapt. Overall was good.
