Had a really amazing stay at César and Jessica's place. They've done an excellent job renovating the place, it's a very nice space to spend time. High ceilings and high windows let in lots of lovely light. Location is superb, 2 mins to a huge Sainsbury's, 2 mins to Whitechapel station - which gives fast access to much of the city. Many great pubs, cafes and restaurants nearby. The roof terrace is epic - huge, and with 360 degree views.
Couple of things to be aware of, although we were not at all bothered by them. The apartment is directly above Whitechapel Road and very close to the Royal London hospital, so there is a lot of street noise and sirens at night. But this also means you're above a very lively part of the city, with lots to observe out the window, which we loved. Our 3 year old slept through it all too, so it can't be that bad :)
César and Jessica were excellent hosts, very thoughtful with their instructions and information on the area.
Overall, a really amazing stay. We loved it, and highly recommend it!
