Jan and Victoria are a happy young couple who welcomes you since the very beginning when you enter their adorable house. The room upstairs is very spacious (about 20-25 square meters) and bright (with a panoramic view of the street), absolutely as it was described in Airbnb and even better. The interior is rather simple, but well-organised. Fits easily for two persons. Convenient enough. Newly-refurbished bathroom (like in 4-stars hotels, for example, Sheraton). New&modern washing machine in the garage.
Thornton Heath is a lovely city area filled with townhouses and no high buildings like modern apartment blocks.
People all around in Thornton Heath are very friendly and kind. Good infrastructure: railway station and Tesco's grocery shop - just 3-5 min, Waitrose at East Croydon, plenty of restaurants,bars,shops at Clapham Junction (all about 15min by train). I recommend an authentic Italian restaurant - MetroPizza at Clapham Junction, and a Telegraph pub (serves no food) for a pleasant conversation, just 2-3min away from the house.
The only two things I suggest are replacing the old pillows (a new one costs just £10-15) and installing a door lock with a mini-latch inside for the night-time (which are usually the common things both for hotels and bnb's).
For the next tenants I have left plenty of useful things: shoehorn, AC adapter, tea accessory, a bottle opener (for the wine), five (or six) wooden hangers, stain remover, etc.
I recommend Jan and Victoria to everyone who visits London/Croydon up to 3 months. That was a pleasant stay.
Thank you, Jan and Victoria!
