We recommend the place and we would return, only a few things that we were not aware of:
The check in is at 4.00PM and not at 3.00PM
Free car parking is advertisied but I did not know that we have to let the owners know in advance that we will want to use it, and there is a £50 refundable charge that is to be paid as well.
The comunication with Regina is a bit pour as she replies late, but as soon as Andrea D contacted us on email a few days before our stay, she replied very very quickly and she helped us with everything, thank you Andrea.
Tha aprtament itself looks very nice, it has 2 double bedrooms, 2 bathrooms, 1 large living room and is located 2 minutes away from Colindale tube station.
