Marta was very accommodating for me and my boyfriend when we flew in early in the morning. She let us check-in early and leave a little later the following afternoon. The room was also a 10 min walk from a couple different bus stations. Which was very helpful!
The neighbors were a little noisy at night, but nothing that can be helped. We brought earplugs, so we were prepared.
Overall, a great place to stay for a quick stop-over in London!
