We loved the apartment. Great value and perfect location. For us a great opportunity to join the queue of AELTC early (about 15 minutes walk to the courts and 30 minutes to the queue) But also when there is no championship it is a great location with shops and restaurants nearby and bus stop directly in front of the house and a 15 minute walk to Wimbledon station.
The apartment is clean and nice, however there are a few things you should be aware of: Windows could need cleaning and we didn't manage to open the ones toward the street.
It was very noisy at night, because the windows weren't isolated very well. The kitchen and living room is nice and well equipped, but there are some water stains at the ceiling.
Communication was good, the check in and check out smooth. We appreciated the opportunity to leave our luggage before the check in time. We had a perfect stay and would choose the apartment again when staying in Wimbledon.
