I will start with the good things.
1. check in was very easy at the Leonard, the flat is directly across the street from the check in location, and Paul was a great host.
2) the location was fantastic. The Marble Arch tube station and bus stops are very close walking distance to the flat.
3. there is a fantastic coffee/ breakfast shop right on the corner to the right of the flat when you exit.
4. the streets all around the flat felt safe to walk on day and night. We are a family with 2 children.
5. the master bed was comfortable, and my children didn't have any trouble sleeping on the bed in the 2nd bedroom or on the pullout couch. I can't attest to these beds for adults though.
Now for things I didn't like:
1. the flat is very old and outdated.
2. the carpet is stained in several places. I didn't want to walk on it without shoes.
3. the couch is old and grubby. We had it pulled out to use as a bed for our son during our stay, so we didn't sit on it, but I would have wanted a sheet over it if we used it for seating.
4. the other dining style chairs in the living room are very cheap and wobbly, and 1 felt broken. We didn't use these chairs.
5. The only time we were in the flat was to get ready in the morning and to sleep at night. I would not have wanted to spend any time in the flat other than those times because it's just not cozy, clean-feeling, or inviting.
If the owner spends time/money updating and refreshing this flat, it could be really cute. If you book this unit, know that it is functional and works as a home base, but don't expect to want to spend a lot of downtime there.
