Nice basic room inside a guest house with an obviously great location. Oscar is very responsive and proactive in terms of check-in, luggage storage and recommendations for the city (you will receive a nice personal map on Google maps with lots of suggestions for your stay, whether long or short!), which can be really helpful.
During our stay one shower was broken, which left us with two showers for the whole guesthouse so we had to wait with showering few times. Also the cleanliness could have been slightly better, as the pictures left a different impression on us beforehand - this also applies to the bed mattress in our room, which is thinner than it looks like on the pics.
Still had a fun time and it's a good basis for easily getting around the city!
