Mono's house is in an excellent location.
Geographic advantage: It takes 5-7 mins of walking from the station - Poble Sec (Line 3). And it's not far from La Rambla, maybe 15 mins of walking, or you can take the metro of 2-/3- stations in Line 3. On the back of the house, there is a mountain. Wow, that's a good choice in our trip because there is a big football field where you can see the daily life of local residents.
Environment: Mono has a lovely terrace full of plants, from which we can enjoy the sunrise and sunset of Barcelona.
House features: Mono's house has many art works. If you want to know more, just come and experience it by yourself.
Last but not least, I'd like to say thank you to Mr Mono and his wife. Thanks for your hospitality and kind advice so that I can have such a wonderful and secure personal trip in your country. Wish everything goes well with you forever.
