I stayed at Astrid's app for 6 days. We emailed sometime before my arrival and she gave me all info I needed. She was so welcoming and on arrival showed me around the flat and even a small tour round the area.
The flat is in a lovely and safe area, and as a single traveller a great place to stay. 1-2 min walk to cosy coffeshops, tubestations (warren str and great portland str stations),shops and pubs. You could choose to walk downtown which doesn't take long. A 5 min walk to lovely Regents prk. Just grab a coffee on the way and relax.
The flat itself had everything you would need, working wifi in all rooms, enough hot water for a bath and more. Washingmachine was easily managed. A quiet street and no noise from neighbours. Some buildingwork going on next door, but I was aware of it before I got there. Didn't bother me as I was out all day anyway.
She lives on the 3rd floor, but no problem climbing the stairs.
Astrid is a warm and friendly person, I would recommend her and her flat to anyone. I would definately rent this place again!
