Maryana's flat is a comfortable and secure place in a lovely location that is great for a long term stay. Whilst moving to London from the States, we spent our first month here. The floor to ceiling windows are spectacular and the view is truly peaceful. We loved having Haggerston Park across the street. To be right in between Columbia Rd and Broadway Market is fantastic -- two of the best markets in the Hackney area. Maryana is pleasant and quick to respond to messages also.
That said, there were a few minor drawbacks to be aware of. Unlike many current Airbnbs, there is not an automatic lock or check-in system, meaning that we had to arrange a time to arrive and to return the keys when leaving. After initially booking, we were informed that the flat would not be ready until 20:00 due to cleaning (unlike the listed 10:00 check-in time), which meant we needed to book alternate arrangements for our first nights in London.
We also found that several standard essentials were not available: hand soap, shampoo, iron, wastebin, or bags for waste.
All in all, we had a lovely stay. I would recommend Maryana's spot as a nice place to put up guests if you are local to the area, or if you plan on staying and settling down for a while as we did, but I wouldn't suggest it for a brief visit if you are coming in from out of the country.
