i stayed for 5 nights at Susana's place. A lovely, quiet and welcoming space that has all the amenities that a traveller could need- a good sized bedroom, very comfortable large bed, cupboard space, a nice fitted out kitchen and dining space and a comfortable, large and clean bathroom.
2 things really stood out for me-1) the location is really priceless. A couple of mins walk to the beautiful Kensington Gardens and Hyde Park, a 3-4 mins walk to both Lancaster Gate and Paddington stations. From here every place in the city are very accessible.
2) Susana is a really great host- she is warm and welcoming but also really mindful to not intrude into your space. We had some great conversations too which I enjoyed.
In all, I can't recommend this place highly enough.
