The accommodation was very good, the bedroom felt private and the bathroom (with good sized bath and shower facilities) was spotless. The host Evangelos has his own on suite bathroom so although the guest bathroom was not on suite it did feel like it was was our own. Access to the apartment was easy and to get there we just caught the tube from Euston to Green Park then the no. 19 bus (stop is just outside the tube station) to Cheyne Walk, then about a 4 minute walk to the apartment.
Evangelos was very courteous and helpful and not at all intrusive, we felt very comfortable using the other facilities in the apartment. All in all a great stay in London.
