This is a lovely, well-appointed and tastefully done up flat in a nice residential area close to the city centre.
Maida Vale is a rather affluent neighborhood, so it is safe and quiet. There is a bus stop just around the corner (served by three bus lines) and the tube station is a five minute walk away (Bakerloo line). Taking the tube it's about ten minutes to Oxford Circus, so not far at all. There is also a small supermarket next door, where you can buy pretty much everything you need (they even top up Oyster cards).
The flat itself is in a lovely old building but has been renovated and furnished to high standard. There is a fully functioning kitchen, modern bathroom, one bedroom and a living room with a sofa-bed. Both beds were comfortable (though quite creaky, especially the sofa-bed - if two people are using it they might be keeping each other awake). There is a TV as well as wifi and even a dishwasher in the kitchen.
The contact with Vincent was nice and easy. He was always quick to reply and very friendly.
If we had one issue at all, it was cleanliness. Not that the place was very dirty, but the cleanliness could definitely have been improved upon, especially in the kitchen and bathroom. We took a sponge to it ourselves and it was fine after that, but considering how nice that flat is otherwise (and quite expensively done up for an airbnb-apartment), it was a shame that the cleanliness had not been up to the same standard.
Otherwise we had a great stay and would not hesistate to come back!
