It’s a house with a few different studios, and the one we stayed was exactly as advertised, small but had all the ammenities we needed, great clean bathroom and a kitchen with a few supplies. Just be aware that you’ll need to carry your bags over one or two flights of stairs, but that wasn’t a big hassle since we only had to do it twice.
The host was super available to us when we had any needs or doubts during our stay, and he kindly let us leave the bags in the house after checkout since our flight was later in the day.
The location is wonderful, really close to Hammersmith station which gives you access to many parts of Central London in 20-30 min and is relatively close to Heathrow (about 40 min tube ride via Picadilly line)
Definetely would stay here again!
