The accommodation is located in the Recoleta neighborhood. I think this is the best part of the city. This part of the city is fine for walking about - either with a plan or aimlessly.
The wifi worked well without a single interruption in the 6 weeks I stayed here. It's also a quiet location both during the day and at night.
Many of the tourist sites are reasonably close or within walking distance. There are also Metro and bus stop sin the vicinity though I didn't use either mode of transport.
All in all, a nice play to stay in the best area of BA.
