We have stayed for a month at plenty of AirBnb properties, and Michael's apartment was easily one of the best, and one of the few which we would definitely stay at again. The area surrounding it is excellent, with everything within walking distance, including a few major metro stations. There are several tapas bars and restaurants within 100m, but the double-glazed windows are quite soundproof and you can barely hear anything from outside. The apartment has all of the personal touches that make it feel like home from the moment you step inside. It's very well stocked with many day-to-day items that a lot of rental apartments forget eg. paper towels, cleaning products, Tupperware, body wash and plenty more. We didn't need to buy anything except food (although there were some welcome fruits and other things too).
The wifi was fast, the bed and futon couch was comfy, the shower was hot with great water pressure. The bed was slightly small for 2 tall people though. Overall: A+ rating
