I booked a three day stay with Ashaa with a little bit of trepidation, because she was a new host, and the only review on the site wasn't great. However, when I arrived, I found that feedback to be totally unfair. The room is EXACTLY as pictured, and is so big that I wondered if it had been a living room. The sheets and blanket were fabric-softener fresh. The towels provided were actually functional for people with long hair (a rarity for Airbnb). The bathroom is large, and very clean (and has great water pressure!). Ashaa handled things very professionally, and was very solicitous about my needs--I was surprised that she was so new to Airbnb. She offered me use of the washing machine, as well as the kitchen. There is enough storage space in the wall cabinets to fit my whole house. The other flatmate is kind and quiet. It is a night-owl household, but they never get too loud, and they wind it down by 12ish. It's in Zone 4, but is only a 13 minute train from Euston, and then less than a 10 minute walk from the station, so it's an easy to get-to location--not to mention safer and quieter than staying in central. There is also a shopping centre within a 10 minute's walk.
Honestly, I suspect that the only reason that this property is so cheap is because it doesn't have many reviews yet. So book now before she realises how great it is and the prices go up! ;)
