I stayed in Lvy's appartment for 2 weeks in May 2017. I would totally recommend it and would select it back again if I go to London.
The appartment is as it is seen in the pictures. It was very clean, has everything you need for a long stay. The room is nice, has a big desk and natural light. I stayed 2 weeks and Lvy's provided with a cloth wash. The breakfast is included, good enough to save money in such expensive city.
The WIFI is really fast and stable.
The neighborhood was much better than I had thought. It has great night life (Pop Brixton is 1 min walk and has plenty of nice and healthy food as weel as draft beers all days!). It is also very close to Victoria's tube station that has the best London's frequency and makes all connections easier. After the tube closes (11:30 pm during weeks) you can take any bus from or to London downtown area without any issue. I Always felt safe in Brixton and the rest of the city.
Both appartment and neighbourhood provides excelent quality/price balance. Totally recommended.
