I would suggest you to stay in George flat ‘cause he is so kind and easygoing. The house is really close to downtown ( 20 minutes by metro To get time square !). The area is safe but I saw few not nice faces around the metro at night . Better to take a taxi or uber.
The apartment has enough space for 3/4 people, but it is not the best if you want to cook because there is not a kitchen table and there are only 2 chairs. I hope it will be improved the number of new pans and pots, and I wish the housekeeper will improve the cleanness to keep higher the value of this nice and comfortable flat.
