We stayed at Bruce's studio for 5 nights. The place is very cosy and clean - perfect for a couple. The kitchen was stocked with coffee and lots of locally made muffins and the aircon made a big difference as temperatures were quite high in Madrid. Bruce was great to communicate with and getting in the studio couldn't have been easier. Chamberi is a nice and quiet neighborhood full of cervecerias and small shops and is definitely worth walking it. You can easily walk to the city centre too but alternatively, the nearest metro station is only a minute away from the studio. We had a great time in Madrid and will definitely stay at Bruce's again the next time we visit!
