The location is excellent, well located to easily get to Portland St / the center / Piccadilly train station.
The apartment is also a nice one and spacious. The living room/dining rooms is a great area to relax. You can also make use of the kitchen if needed. One of the guest bedrooms is very big, en suite and I had a good night's sleep. The other guest bedroom is a bit smaller, but I think they slept well too. The additional guest bed available in the hallway (if booked) is not so comfortable.
The host Hiloni was helpful and responsive.
There were a few small things which spoiled it being a 5* stay which I will go through below. Please bare in mind we only stayed for 1 night, so were busy most of the time visiting Manchester and so needed somewhere comfortable for the night, so could not really have time to get any of these fixed during the stay.
There was about 1ml of shower gel left in one of the bathrooms, and none in the other, although there was plenty of shampoo, handwash etc which was good. The kitchen door handle is loose, so if you try to close the door the whole handle comes off, the door handle for the living room is similar but does not fall off. The fans are noisy and rattly. Due to the scaffolding it does not feel so light and airy, we kept the blinds closed for privacy just incase there was any work going on directly outside (there was no work directly outside while we were there, only in another part of the building). Due to fair wear and tear the bathroom has mould on the grouting, both toilet seats were loose, and the flush handle for the toilet didn't always operate properly (e.g. handle would feel loose, or not lift on its own etc). The camera at the entrance hall was a bit unnerving, and I do not think it is a very nice thing for guests to see coming in.
All of the above are very small and could be nitpicky things, but all combined it does make you feel that the stay could be improved. I think the location, space and value could mean that this is the right Airbnb for you! The parking is also a plus. However for me, I would not stay again even though it was an overall good stay considering the value.
