the apartment was amazing ground floor right in the town centre next door to Tesco's, so no need for a fridge but had one anyway, own secure parking
I stayed 2 weeks for a treatment in a clinic in Letchworth and this apartement is a great place if you wish to be able to take care of yourself, to cook your own food, have close access to the train (5 min walk), to wash. Another advantage is the Tesco supermarket 1 min away open 24h.
Slightly negative is some noice from outside (train, flights and people) but I still slept well. Also the surrounding area and shopping center is quite boring.
Only 35 min by train to Londons Kings Cross.
Excellent and quick respons and service mindness of the landlord in case of any concern.
