This is a hostel type style accommodation. We were shocked when we arrived to find this.
You do have a private room, however you are sharing this house with 6 other private bedrooms. You are not staying in a place with Matt and have no communication with him. You talk to a woman named Ella during check-in/check-out. They have strict rules with check in times. Ella is kind and helpful when needed. All communication is done via airbnb messenger or text, unless of an emergency in case you have her phone number.
I would not have booked this room for my mom and I, if I knew that this place was a hostel style housing. Description is not very clear. Since we were only staying two nights and the place was clean enough, we decided to stay. One of the bathroom floors was completely filled with water and unusable. Personally, I think that 5 days of cleaning is not enough for this style accommodation. At least in terms of the bathrooms. The bedroom and kitchen were very clean. The room is small - so if you have 2 big pieces luggage I would suggest avoiding this room. My mom and I managed as she was the only one with a big suitcase, but it was cozy. Location is great though, it is a 5 minute walk to the underground.
During our stay guests from another room came in around 3 am one evening and were incredibly loud, clearly drunk. So if you are looking for somewhere that guarantees quiet - this would not be the place.
