Silvia is an awesome host, she is responsive and very friendly. The oyster card provided for public transport, free coffee from Pret and most importantly, sending up a fan during heatwave, are all very considerate and out-of-surprise service beyond the description here.
The apartment is located very close to the city centre, a stone-throw distance to the metro station connecting to the Piccadilly line, by which you can connect to the city centre within half an hour.
