We are a family of 4 adults (2 parents, 2 adult daughters) from Los Angeles, traveling through Europe for 8 months since May. This is our 23nd Airbnb stay during this time. We stayed here for 3 Weeks.
COMMUNICATION: The team was quick to respond, gave clear instructions and easy to understand.

APARTMENT: The unit itself is on the 2nd floor (3rd floor for us from the U.S.) up a nicely lit and private staircase. It is one of the best units we have stayed in. It has a modern and luxurious décor, with smart Home features (pretty easy to figure it out from the main panel - just follow the icons). The appliances are top notch (especially the Miele Built-In Coffee Machine). All the materials used in the home are luxurious and are about as 5-star as you can get. The size of the unit was perfect and we never felt crowded - very nice size! The beds are comfortable if a bit hot. The showers are full walk-in's with ample size (not seen a lot of that in Europe). The kitchen/living room in smartly designed and we spent a lot of time enjoying TV while having some meals in. Since we stayed here for 3 weeks we really put the unit through it's paces, and it handled it very well. Wifi is a little weak at times, but mostly good. Only issue is VPN was not usable at all, so I had to go to a local coffee shop to do any business work so inconvenient. Should be an easy fix though. Physically it was a fantastic unit. However, noise is explained further in the next section.
LOCATION: The unit is in the heart of SoHo. Fantastic energy and vitality. We arrived from the tube on a Saturday night and we were blown away by the crowds on the street and the fun vibe. You have to pick up the keys at a nearby location which was pretty straight forward. In general, SoHo is a great location to get to anywhere touristy in London. Easy to jump onto the Tottenham Tube station or Leicester Square (both less than an 8 minute walk). Plenty of taxis also if you prefer (but we really enjoyed the Tube and Buses). At either end of the block are two great pubs. We enjoyed them both and had some good meals in there as well. Plenty of restaurants to explore in the immediate vicinity, and more then enough theaters to enjoy. It really was a great location.
Having said that, personally I think it's a great place to stay for a few days. For longer stays it will be way too noisy. We knew that coming in when we read the other comments, and since we usually are not bothered by noisy street, didn't care going in. But after being there for 3 weeks it wears you down after a week. And it is relentless, non-stop until 2 or 3. The windows are not double paned and the curtains are light, so it sounds as if the windows are open with the noise. And there are some patios right outside the master bedroom that can get loud at times (especially on weekends). Now - if you're plan is to be out there with the partiers, then it's fantastic. But if you're trying to get some sleep at around 11 or so, it will be very difficult. Again, it's totally ok for a few days.
This was a fantastic unit with features and amenities right up there with the best we've ad in Europe. Location is great and you can get anywhere in short order. And the host was great. I highly recommend the unit for a short stay.
