Best Sauna in London, hands-down. Coming from Germany, its very hard to find good Sauna places in London. Banya No. 1 has never disappointed and is one of the very few good options in the city. The Sauna is built to proper standards and I guarantee that on the top-row even tenured Sauna-goers will start to sweat properly. Plunge pool has perfect temperature.
