Marta is such a gracious host, very great at communicating and making sure you're doing perfectly throughout the whole stay.
Her flat is beautiful, cozy, tastefully decorated, with everything you might need. Special mention for the bathroom ! the showerhead is great, and the deep bathtub even better.
The only drawback is that the walls are pretty thin, so you will hear the neighbours a lot - beware if you're a light sleeper.
The neighborhood is great, Dalston is such a pleasant, cute, vibrant place, with lots of lovely pubs and cafes, and all buses and tube stations accessible within 10min.
