I had a great stay in Mono's apartment. He and his wife are very welcoming hosts and their apartment is full of colour and art. The location is ideal -- it feels like a really local neighbourhood, not touristy, and very safe to walk around at night. In two minutes, you can be on a main street with bars and restaurants; in about ten minutes you can be at Parc Montjuic, the national art museum, or avenue Paral-lel in the other direction. It's very walkable to the Gothic Quarter and Born. The bed is also really comfortable! Mono was extremely kind when my arrival flight was delayed in the middle of the night and I appreciate that he wanted to help me even outside normal check-in hours. He also helped me get my luggage up and down (the apartment is on the top floor -- amazing view but 100 stairs -- very good exercise)! The only thing I would note is that if you're very sensitive to cigarettes, they do smoke in the toilets but it doesn't affect the rest of the apartment. I had a fabulous stay on a great budget! Thank you, Mono and Peka!
