Location is EXCELLENT for exploring London. We stayed for two weeks and most everything we wanted to do was one tube or bus ride away. Four bedrooms and three bathrooms (first bathroom has shower and sink only, second one has shower/tub, toilet and sink, third has toilet and sink only) and four bedrooms. Can't beat the price.
This unit has no A/C. We stayed in June and it was uncomfortably hot. Had to keep the windows open (flat has a fan for each bedroom) and Drummond street has an active nightlife. On Saturday nights the music and screaming and singing and fighting went on past 1am (just the neighborhood - nothing the host can do about that). Hot Pepper Cafe open for breakfast and lunch right below the flat is great. Lots of Indian restaurants nearby. Within quick walking distance to Euston Station or Warren Street Station tubes. Two small grocery stores and a pharmacy nearby.
Communication with host was tough - I didn't have cellular data and host didn't see emails. Requested a second set of keys, did not get them. Kitchen sink had a constant drip, smell of mold in the bathrooms. Oven was broken when we arrived, he sent a handyman to fix it. It was nothing deal-breaking.
Another review mentioned the sound of the tube underground. Yes, you can hear it, but it's minimal. Never woke us up.
Can't beat the price for being so close to central London, and even with everything that happened I would stay here again (in the Fall or Spring when not so hot).
I missed the personal touches of other Airbnb's - no welcome book with suggestions nearby, no instructions on how to use appliances, the Wi-Fi password provided was wrong but I guessed the correct one. One towel per guest, but large and clean. It felt transactional, and less personal here. This is definitely a business for host. Londoners didn't like that we were staying at an Airbnb, apparently it drives rent up for them.
