Our stay has been great and Markito is a very kind and helpful host and perfectly organized. The place is well equipped and very clean and tidy - much better than most other accommodations I've seen in London. There is a 24 h bus stop just in front of Matkito's place that connects you to the party spots in Shoreditch in 10 to 15 minutes and also to Victoria it doesn't take you more than 45 min.
All in all a full recommendation. The only small disadvantage is a very busy street just in front of the window (at least in one of the two rooms he rents out), which is a bit noisy. So if you're sensitive, bring some earplugs and you should be fine.
You can safely book this place!
