Our stay was good. The apartment is a bit old but renovated. It may need a few fixes but nothing remarkable. It’s good for two people, ok for three but I don’t think four people would have a good start, since the double sofa bed is not very confortable (the bed is).
The location is great, since it is walking distance to the tube, restaurants and supermarkets.
Note it is a basement, so you have to go down a few steep steps to enter the unit. We did it with a push chair, but it can be a challenge for a person with disabilities.
