We enjoyed our stay at Alessandro's studio. The self check-in process was easy, thanks to Alessandro's helpful instructions. The studio was very clean and comfortable. We shared the bathrooms with just one other room and it worked well (there are two bathrooms on this floor - one with a shower and toilet and one with just a toilet). The trek up the steep stairs can be a bit tiring, so be ready for that, especially if you have heavy luggage! :) We enjoyed the Pimlico neighborhood and would stay here again if we return to London.
