This studio is a good value-for-money deal. The location (5 minutes walking from Central, Circle and District tube stops, next to Hyde Park) is amazingly convenient if one wants to move within the zone 1. The communication with Ali was swift and precise. On the downside, the studio is in a basement (as stated, we knew it!) so air does not circulate properly. The cleaner that came before we entered apparently dropped some heavy scented detergent on the table. When we entred the (bad) smell was so strong we just wanted to leave. I gave three star for cleanliness for this matter, as well as for the presence of dirt right under the bed. I hope this will be fixed in the future for the upcoming guests.
