Nina's place is great. The room was spacious, definitely enough for two people + 4 of our luggage on the floor (the room was this spacious). The entire apartment was sparkling clean, and Nina was very accommodating when it came to our request. She was also easy to communicate with.
In terms of location, bus B44 was a corner away. This bus takes you to the subway. There are a couple of small markets nearby for you to buy food and toiletries.
