Top-notch ! The location is perfect in safe and chic South Kensington. A 8 minute walk to South Kensington or Sloane square tube stations. Nell Gwynn House is a newly refurbished 1930 building with a 24/7 friendly concierge which makes it very convenient to leave the key each day. No risk to lose it! The check in was very easy and the women working in the office are extremely friendly and helpful. The studio itself is like a 5-star hotel room. Remodeled a few months ago with modern and high standard feature, it is small but has everything you would need. It is facing a quiet back street with an open view which gives a lot of light. Great comfortable bed, a big flat screen TV with hundreds of channels plus Netflix, fast internet, a brand new bathroom with a wonderful walk-in shower and fluffy towels. The only “complaint” I would make is being charged 5.00 £ for an extra set of towels and the tedious inventory. It was a wonderful stay. Thank you Charlotte and her staff for your kindness and availability and to the nice concierges too.
