We stayed one week at this apartment.
Positives: It was very clean, newish furnishings, although the sofa needed a good cleaning, and new looking kitchen and bathrooms. Two bathrooms are a rarity and this was a must for us (3 people) so this is one of the reasons we chose this rental. Location is excellent, a bit noisy at rush hous because it is just across site street from the station, a huge positive for us!. Two exits on the rail from Covent Garden station. Lots of good restaurants, moderate to expensive priced, and lots of pubs. Small convenience grocery stores are down the street (expensive) but very convenient. A great library of books and England travel guides are at your dispose. The security is excellent and there is an elevator.
Negatives: No air conditioning and there was an unusual heat wave. There were two tiny fans that did not help. The window in the master bedroom opened to the back of a restaurant so with windows open the room smelled of fried fish :(((
The Internet was not the best , we had to reset it in order to connect and sometimes it did not work at all which was frustrating as it was very important to us to be connected.
There were only 3 bath towels provided and it was not ideal to use the same towel for a week.
The "washer" was a tiny apartment size appliance and not very helpful and there was no good place to dry clothes except on a rack provided in the living room near an open sliding glass door. Also when we tried to wash the bath towel, they were hard, grey looking and scratchy due to the poor washer and lack of dryer.
In conclusion, we would definitely stay at this apartment in any season other than summer. We loved the city and the people and this was one of the best vacations we have been on!
