Overall this apartment is great. We stayed for two weeks with four young children ranging 1-8 YO.
The apartment is spacious and comfortable, the beds and pillows are very cozy, the kitchen is well equipped, the living room is very pleasant including TV, couches, and dinning table.
The location is perfect for those who are looking to be close to (Kosher) a bakery, restaurants, coffee shops, supermarkets, and of course the Tube and buses are convenient walking distance.
Yossi was very responsive and provided everything we asked for, and even reached out on his own a few times to make sure we weren't missing anything.
