We spent two nights (18$ per night) in a double room in the Giang Son guesthouse. We made a reservation by telephone two days in advance. On the first attempt we went past the small alley the hotel is situated in, but found it on the second attempt. The staff was english-speaking and very nice and helpful. The rooms were clean and too spacious but had enough space for our 2 backpacks. It has a nice terrace on the sith floor where you have nice view over the surrounding buildings and is perfect for a having a last beer of the day ! It is very close to the park and most of the sights are in walking distance. Around the corner the street is full of nice bars. We booked the Cu Chi tunnel trip through the hotel which was fine. After the trip we were allowed to take a shower despite we weren't going to spent another night in the hotel. The hotel also arranged transportation to the airport. Overall we were very satisfied with this guesthouse!
