Stayed for 10 nights. Everything we found was as expected in the ad. The hosts were really good with their communications with quick responses and very useful information. The place is very clean and tidy, has all the basic amenities that made our stay confortable. We loved the old heritage style of the unit with all modern appliances. Just as per clearly advertised, the access to the unit is via some narrow and steep stairs going down which are not too bad, but just something to consider if you have physical limitations.
The unit is located in a nice and quiet and lovely neighbourhood, about 10 minute walk from Hammersmith underground train station, and close to a number of pubs, restaurants and shops, so all very convenient.
We do recommend this place, and will stay again next time we come back to London.
