We stayed 2 nights. The location was well suited to our needs. This was our first AirBnB experience as well.
Pros:
Dayana is really a great host and made us feel welcome from the start. Warm lighting and scented candles welcomed us in. Our room was small but spotless, exactly as the pictures showed. Our hosts were careful to respect our privacy, and were generous to hold our bags even after checking out.
Cons:
The spaces are quite small (London!). A temperamental electric shower would suddenly douse us with freezing water without warning. Limited sound insulation meant loud thumps sometimes woke us up late at night (I guess my snoring was responsible!).
Advice:
Overall, we had a nice and easy stay. Groceries and co-operative stores are <5 mins away. The hosts are friendly and extremely helpful. If the location and room size suits you, go for it without thinking twice!
