This was tough to review as so many other guests have said nice things about their experience - I will leave it to potential guests to decide.
Sylvia was a very friendly woman who communicated with me in a timely manner and was available for several nice conversations during my stay. The location is okay, but it requires a 10-15 minute walk to the 159 bus stop that will take you to the heart of London in about 45 minutes.
There are some challenges with this unit - most of which can be fixed.
First, as mentioned by another guest, the description of the unit needs to be amended. The bathroom is shared - not private. The room is not large but actually quite small with a sloped ceiling on one side. The "desk" is actually a tray table with a rusted lawn chair to sit on. The fridge is a small table top unit that didn't keep anything cold even when put on the highest setting, resulting in spoiled food. The fan provided did not work.
I mentioned these items in my private review to her in hopes that proper changes can be made to make this a better guest experience.
Things that will remain challenging are the small size of the room, the fact that it gets brutally hot in summer (I was there in June), and the staircase leading up to the third floor is steep, tight, and winding, making for a difficult time in lugging a suitcase up or down the stairs.
Still - this unit has garnered several positive reviews. This was my experience. As mentioned you'll need to decide whether it would be suitable for your needs.
