We were a large group that had specific requirements: 6 adult women, each with her own bed and we needed a minimum of 3 bathrooms. I had searched various options in London, and came across LSA. At every step of the way, from initial inquiry to a fix in the apartment itself, I was met with prompt, polite, helpful responses. Additionally, Giavanna (LSA agent) answered all questions from individuals in our group, and explained everything to me very clearly with respect to charges, check-in/out policies. Beyond this, the charge for a 4 bedroom apartment in Earl's Court came to /less/ per night for each of us than if we had stayed at the hostel down the road. The accommodations themselves were very nice, very comfortable for our group. Niggling problem: WIFI was poor in all but the rooms closest to the door, so there was no usable connection in the kitchen and 3 of the bedrooms (out of 4.) For my purposes, this meant roaming data was a must where it would have been optional otherwise (an added cost, but not a deal breaker.)
