Our stay at Hilda's place was absolutely great! It is very easy to get into the city center, as there is a bus station right in front of her house. (15 minutes by bus and tube to Victoria) Brixton is really great part of London with lots of restaurants, pubs and a nice park.
The room was exactly as described and how it was displayed in the pictures. The bed was really comfortable and really the only thing that wasn't that nice was the shower, because the water wouldn't heat up and it was really cold. But we already knew before coming that there were problems with the shower so for us it wasn't that big of a problem. :)
We would absolutely recommend staying at Hilda's and hope that maybe we can come back another time.:)
