The location is great, especially if you're flying in from Gatwick. You do need several busses and metro's to get into the city centre. But bus stop is right next to the house.
The room itself was spacious and you can also use the kitchen and bathroom (you do have to share with other guests). That's why it feels more like a hostel than an airbnb place. It also wasn't very neat or clean (filthy rug in our room really doesn't need to be there ;) but if you're okay with that, the place is fine. Communication with Lina was good, I got great instructions for checking in and she was helpful with other questions as well.
